President Donald Trump mocked Democratic leaders Charles Schumer and Nancy Pelosi by addressing reporters while seated next to two empty chairs after the Democrats skipped a White House meeting with him.

Trump staged a photo-opportunity designed to humiliate the Democratic leadership after they snubbed a White House meeting where a looming government shutdown was on the table.

The two leaders announced they would skip it after Trump went after them in a morning tweet.

Trump then met with Republican leaders Mitch McConnell and House Speaker Paul Ryan. When he spoke to the press afterward, the president was seated between two large, leather chairs – each in front of a nameplate of the Democratic leader to signify their absence.

'We are very far apart,' he said at one point.

'So they decided not to show up. They’ve been all talk and they’ve been no action ... Now it’s not even talk.'

President Donald Trump, surrounded by empty chairs marked for U.S. Senate Minority Leader Chuck Schumer (D-NY) and House Minority Leader Nancy Pelosi (D-CA), who chose not to meet with Trump, Senate Majority Leader Mitch McConnell (R-KY) and House Speaker Paul Ryan (R-WI), speaks with reporters at the White House in Washington

The president then tore into the no-show Democrats. 'I’m not really that surprised,' he said.

'I'm not really that surprised, we have a lot of differences. They are weak on crime, they're weak on illegal immigration, they want the illegal folks to come pouring into a border and a lot of problems are being caused, although we've stopped it to a large extent without the wall, which we're going to get,' Trump said.

He repeatedly stressed national security, and brought up a Tuesday missile launch by North Korea.

'They, before this meeting and before this missile launch, have been weak on military in terms of spending. They're very hard to get for military. They want it for a lot of other things, but the military is always secondary to them,' Trump said.

'And the other thing, they want tax increases and we want major tax decreases. So they decided not to show up. They've been all talk and they've been no action. And now it's even worse. And now it's not even talk. So they're not showing up for the meeting.

'I will say this, in light of the missile launch, probably they'll be here fairly quickly, or at least discussions will start taking place fairly quickly,' Trump added, without explanation.

'We have a lot of differences. They’re weak on crime, they’re weak on illegal immigration,' Trump said.

'They’ve been weak on military in terms of spending,' Trump said.

The two top Democrats in Congress abruptly canceled a planned White House meeting with Donald Trump on Tuesday in response to the president's angry tweet expressing pessimism about their willingness to cut a deal that would keep the government running.

UNCOMFORTABLE: Schumer and Pelosi skipped the meeting after Trump called them 'weak on Crime'

THERE WAS GOOD COMPANY, GLASSES OF WATER ... The lawmakers skipped the meeting after Trump went after them in a morning tweet

Trump threw shade at Sen. Chuck Schumer and Rep. Nancy Pelosi hours earlier, calling them tax-hikers who are 'weak' on crime and favor the 'unchecked' admission of illegal immigrants into the United States.

And he wrote that he doesn't 'see a deal' in the making.

Pelosi and Schumer effectively cut the president out of the conversation late on Tuesday morning, saying in a joint statement that '[g]iven that the President doesn't see a deal between Democrats and the White House, we believe the best path forward is to continue negotiating with our Republican counterparts in Congress instead.'

House Democratic Leader Nancy Pelosi abruptly canceled a budget- and tax-related meeting with Donald Trump on Tuesday, saying she won't go to the White House after the president tweeted that he was pessimistic about cutting a deal across the aisle

Chuck Schumer (center), the Senate's leading Democrat, is also boycotting Trump, essentially cutting the president out of buget negotiations

'Rather than going to the White House for a show meeting that won't result in an agreement, we've asked Leader McConnell and Speaker Ryan to meet this afternoon. We don't have any time to waste in addressing the issues that confront us, so we're going to continue to negotiate with Republican leaders who may be interested in reaching a bipartisan agreement.'

Senate Majority Leader Mitch McConnell – who has also been on the receiving end of Trump twitter attacks – and House Speaker Paul Ryan hit back with their own statement bashing the 'new excuses' not to meet with the administration.

'We have important work to do, and Democratic leaders have continually found new excuses not to meet with the administration to discuss these issues,' the two leaders said. 'Democrats are putting government operations, particularly resources for our men and women on the battlefield, at great risk by pulling these antics. There is a meeting at the White House this afternoon, and if Democrats want to reach an agreement, they will be there.'

The back-and-forth on the budget came as Trump visited Republican senators as they rush to take up a $1.4 trillion tax cut bill.

The Senate Budget Committee reported the legislation on a party-line vote of 12 to 11. It included the votes of two Republicans who had raised doubts, Sen. Bob Corker of Tennessee, who raised concerns about the bill's effect on the debt, and Wisconsin Sen. Ron Johnson, who complained about the impact on smaller businesses.

As the bill heads toward the floor, leaders are continuing to adopt changes to lock down votes.

President Trump tweeted about an upcoming meeting with Sen. Charles Schumer and House minority leader Nancy Pelosi

'It's a challenging exercise,' admitted McConnell. 'I think I'm sitting there with a Rubik's cube trying to get 50 [votes]. We have a few members who have concerns and we are trying to address them. We know we are not able to go forward until we get 50 people satisfied, he said.

Maine Sen. Susan Collins blasted the inclusion of the repeal of Obamacare's individual mandate.

'I continue to believe that it was a big mistake to combine that provision with tax reform,' she said, but indicated her concerns had been met through the guarantee that Trump would sign legislation to prop up the market before any final tax bill conference report comes to a vote.

'A lot of my concerns, it appears, are going to be addressed,' she said.

Sen. James Lankford (R-Okla.) said he raised concerns about debt issues during the meeting with Trump, which he said was mostly questions and answers from the president.

'The challenge is the what-if. If you have other situations come in you've got to be able to also prepare for the future,' he said.

Sen. Bob Corker (R-Tenn.) indicated that his desire to have a 'trigger' put in place to hold back tax cuts if they don't cause the desired economic growth.

'I think we've gotten a commitment that puts us in a pretty good place,' he said, TalkingPointsMemo reported, citing a 'verbal agreement' he said he got from the president.

The White House told reporters late on Monday that Trump would meet with congressional leadership at 3:00 p.m.

On Tuesday afternoon press secretary Sarah Sanders said in a statement that [i]t's disappointing that Senator Schumer and Leader Pelosi are refusing to come to the table and discuss urgent issues.'

'The President's invitation to the Democrat leaders still stands and he encourages them to put aside their pettiness, stop the political grandstanding, show up and get to work. These issues are too important,' Sanders said.

'The meeting will proceed as scheduled with Speaker Ryan, Leader McConnell and administration officials who are committed to getting things done,' Sanders added. 'If the Democrats believe the American people deserve action on these critical year-end issues as we do, they should attend.'

NO THANKS: Pelosi tweeted that she and Schumer plan to 'continue negotiating with our Republican counterparts in Congress'

Trump is also scheduled to speak with the Republican Senate Caucus at lunchtime.

Republicans have unified control of government, but leaders may need to rely on some Democratic votes to get a funding resolution passed.

Some Democrats are demanding a fix to help DREAMers who came to the U.S. illegally as immigrant children. The president rescinded their status but set a six-month deadline that ends in March to find a solution.

'Meeting with 'Chuck and Nancy' today about keeping government open and working,' Trump tweeted. 'Problem is they want illegal immigrants flooding into our Country unchecked, are weak on Crime and want to substantially RAISE Taxes. I don't see a deal!'

Pelosi wrote that she and Schumer will negotiate 'in good faith'

Trump may need help from 'Chuck and Nancy,' as he calls them, to bring a spending bill across the finish line and avoid a government shutdown for which Republicans would likely catch most of the blame

Schumer responded on the Senate floor Monday. 'Instead of leading, the president tweeted a blatantly inaccurate statement and then concluded: I don't see a deal,' Schumer said.

Trump used a similar attack on Doug Jones, the Alabama Senate candidate who is a former prosecutor and who helped put away two Ku Klux Klansmen who were charged with blowing up a Birmingham Baptist church in 1963.

'The last thing we need in Alabama and the U.S. Senate is a Schumer/Pelosi puppet who is WEAK on Crime, WEAK on the Border, Bad for our Military and our great Vets, Bad for our 2nd Amendment, AND WANTS TO RAISES TAXES TO THE SKY. Jones would be a disaster!' Trump tweeted this past weekend.

'I don't see a deal!' with Democrats to keep the government running, President Donald Trump tweeted

Typically in recent years, even as government funding deadlines approach, presidents reassure financial markets and investors that the U.S. government will ultimately remain open and running.

The president may be trying to use the threat of a shutdown to try to gain negotiating leverage, although usually it is a minority party seeking concessions from the White House who is able to threaten to hold up government funding, rather than the head of the government.

Neither Pelosi nor Schumer are calling for tax hikes, though Democrats are resisting the $1.4 trillion tax cut that Trump called 'tremendous' on Monday.

Republican leaders trying to reach majority support for their tax cut must contend with another conservative who is raising objections, after Montana Sen. Steve Daines raised concerns about how it would affect 'Main Street.'

With just a 52 seat majority, they can only afford three defections from their ranks.

Trump heads to the Capitol Tuesday afternoon to meet with the Republican conference about the tax cut, which could come to the floor for a vote as soon as Thursday.

One Republican senator, Ron Johnson of Ohio, has already said he is a 'no' on the bill because of the way it advantages corporations over so-called 'pass-throughs,' business who file as individuals and miss off on some of the savings in the bill.

NOT THERE YET: Conservative Sen. Steve Daines has voiced concerns about the bill

Senate Finance Committee chairman Orrin Hatch (center-right) told reporters that he 'hopes' to have a tax relief plan on Trump's desk by Christmas, and that he's confident the GOP can find 50 votes to pass it

'Sen. Daines has concerns with how the tax bill looks at main street versus large corporations,' an aide to the senator said, The Hill reported. 'The Senator wants changes to the tax cut bill that ensure main street businesses are not put at a competitive disadvantage against large corporations.'

Daines, a Budget Committee member, linked his support to the issue. 'Before I can support this bill, this improvement needs to be made.'

A new Congressional Budget Office score estimates that '(t)he number of people with health insurance would decrease by 4 million in 2019 and 13 million in 2027' under the bill due to its removal of an Obamacare individual mandate.

That provision has drawn criticism from Sen. Susan Collins of Maine, although it could get removed if needed to lock down enough votes.

Trump hailed the bill as 'a tremendous tax cut' and 'the biggest tax reduction in the history of our country' on Monday.

'I think we're going to have great receptivity. We've had great spirit,' the president said.

'And I can tell you, the Republican senators who are up, if we win we are going to get some Democratic senators who are joining us. If we don't win they wont be joining us,' he predicted.
