President-elect Donald Trump urged Republicans to blame Democrats for the 'mess' of Obamacare, while President Obama counseled Democrats not to 'rescue' Republicans by signing on to replacement efforts once Republicans go through with their plan to repeal Obama's signature proposal.

The countercharges in the rekindled Obamacare wars came as Republicans are planning an immediate attack on the law thorough executive actions and an early legislative push.

Obama went to the Capitol to meet with Congressional Democrats to plot strategy in an effort to prevent his achievement from getting dismantled – a victory Democrats won only at great cost, including with the loss of their congressional majorities.

The president told Democrats not to 'rescue' Republicans by joining their effort to passing replacement measures, amid GOP efforts to court some conservative Democrats.

He pointed to the post-Obamacare Tea Party revolution, and even urged his party to try to brand Republican-backed changes as 'Trumpcare' as a rhetorical way to saddle the opposition party with responsibility for what ensues, CNN reported.

Asked by reporters what he said on his way out of the closed door meeting, Obama said only, 'Look out for the American people.' White House press secretary Josh Earnest said Obama said he felt 'envy' for those who have the opportunity to 'keep up the fight' as he prepares to decamp the White House for a rented home in Northwest Washington.

Republicans, who caucused withe Vice President-elect Mike Pence on Wednesday, are forging ahead with their plan to repeal the law – with Trump planning swift executive actions on the day he takes office.

The new Senate Demoratic leader, Charles Schumer, warned that the GOP's new plan would lead to 'chaos' and mocked Trump's campaign slogan with a sarcastic response, saying Republicans would 'Make America Sick Again.'

Trump kicked off the dustup when he provided political advice to Republicans via Twitter Wednesday morning.

'Massive increases of ObamaCare will take place this year and Dems are to blame for the mess. It will fall of its own weight - be careful!' Trump warned Republicans in one of a series of Tweets Wednesday.

He began his missives with an admonition that: 'Republicans must be careful in that the Dems own the failed ObamaCare disaster, with its poor coverage and massive premium increases......'

Sixteen minutes later, he finished his thought, adding: 'like the 116% hike in Arizona. Also, deductibles are so high that it is practically useless. Don't let the Schumer clowns out of this web...'

It wasn't entirely clear if Trump was stressing that Democrats passed Obamacare without Republican support – all 60 of the Senate votes during its creation came from Democrats and independents who caucus with Democrats.

Pence called for an 'orderly transition' that 'doesn't work a hardship on our economy' in the repeal, but provided no details on which parts of the health law would remain in place or what alternatives Republicans would offer.

He told reporters on Capitol Hill that repeal efforts would 'literally begin on day one' through executive actions.

'Before the end of the day we do anticipate that the president-elect will be in the Oval Office taking action to both repeal executive orders and also set into motion through executive action policies to implement promises that were made on the campaign trail,' he said, without going into much detail.

He later added: 'We're working right now, the White House staff is, on a series of executive orders that will enable that orderly transition to take place even as the Congress appropriately debates alternatives to and replacement of Obamacare.'

'The first order of business is to repeal and replace Obamacare. And that was our message today and it'll be our message on Capitol Hill,' he added.

'Our president-elect took his place to the American people to repeal and replace Obamacare, and the American people voted decisively for a better future for health care in this country and we are determined to give them that,' Pence said.

Pence at a press conference in the Capitol referenced Trump's tweets . 'You read his Tweet this morning that he has admonished the Congress to be careful. And I reiterated that before the Republican conference today. Look, we're talking about people's lives,' he said.

'The president in his first day in office is going to do some level of executive orders related to ObamaCare,' said Rep. Chris Collins (R-N.Y.), an early Trump supporter,' The Hill reported. 'No details whatsoever,' he added.

NO BOZO: Senate Minority Leader Charles Schumer hit back at Trump for his shot at Democratic 'clowns,' saying Republicans 'should stop clowning around with the people’s Medicare, Medicaid and health care'

LIKE OLD TIMES: Vice President-elect Mike Pence, a former House member, left, is welcomed before a news conference on Capitol Hill in Washington, Wednesday, Jan. 4, 2017, by, from second from left, House Speaker Paul Ryan of Wis., House Majority Leader Kevin McCarthy of Calif., and House Majority Whip Steve Scalise of La.

'We don't' want to pull the rug out from under people while we're replacing this law,' said House Speaker Paul Ryan after the GOP meeting.

Trump's shot at 'Schumer clowns' was in reference to new Demoratic Senate Minority Leader Charles Schumer, who in a speech Tuesday warned against a 'Twitter presidency' and tried to rally Democrats to take on Trump when they disagree with him.

Schumer hit back at the tweet in his own remarks Wednesday. 'Well, I think Republicans should stop clowning around with the people’s Medicare, Medicaid and health care,' he said.

Trump pledged during the presidential campaign to erase Obama's law, though he's said he wants to retain popular provisions like ensuring coverage for people with pre-existing medical problems.

Obama's and Pence's strategy sessions were coming on the second day of the new, GOP-led Congress. In 16 days, Trump replaces Obama at the White House, putting the party's longtime goal of annulling much of the 2010 health care overhaul within reach.

'This law has failed. Americans are struggling,' said Speaker Paul Ryan after the GOP meeting with Pence. 'We need to reverse the damage that has been done,' he said.

'Once we repeal this law,' he added, Republicans would provide a 'stable transition to a truly patient-centered system.'

Schumer said Republicans don't quite know what to do now that they have gotten elected vowing to repeal Obamacare.

'They’re like the dog who caught the bus. They can repeal, but they have nothing to put in its place, and that means so many good things go away,' he said.

He accused the GOP of plotting a 'full scale assault' on the Affordable Care Act, Medicare, and Medicaid.

'The Republican plan to cut health care wouldn’t make America great again, it would make America sick again and lead to chaos instead of affordable care,' he said.

Plenty of questions remain, including the repeal bill's details, costs and when it would take effect. Republicans also face divisions over the next step — replacement legislation — that will likely take months or years to resolve.

While they can hardly prevent the GOP repeal effort from proceeding, the president and House and Senate Democrats were meeting Wednesday to discuss how to best defend a law that's extended health insurance coverage to 20 million Americans and which Obama considers one of the proudest pillars of his legacy.

'The more the people understand what's included in the Affordable Care Act and how they benefit from it, the more popular the program is, and the harder it is for Republicans to have political support for tearing it down,' White House spokesman Josh Earnest told reporters Tuesday, using the law's formal name.

Republicans eager to show quick action against Obama's health care law took an initial procedural step Tuesday, introducing a budget bill that would have to be considered under a parliamentary procedure that would prevent Democrats from using a Senate filibuster to protect the health care law.

Republicans control the Senate by a 52-48 margin, but it takes 60 votes to end a filibuster, a procedural roadblock that can kill legislation.

The Senate was expected to complete the budget by next week. House approval would follow.

'This is the first step toward relief for Americans struggling under Obamacare,' said Ryan.

The budget legislation gives congressional committees until Jan. 27 — a blink of an eye for lawmakers — to write legislation repealing major parts of the health care law. Likely targets include the law's tax penalties for people who don't obtain insurance, its requirement that many companies cover workers and tax increases on higher-earning individuals and many health care firms.

Aware they have no chance of quickly agreeing on replacement legislation, Republicans plan to delay when their repeal would actually take effect. A range of 18 months to three years — perhaps longer — has been under discussion.

Trump has provided few specifics about how he would revamp the nation's $3 trillion-a-year health care system. Steps he and congressional Republicans have mentioned include greater reliance on tax credits to help people afford coverage.

Republicans don't want to abruptly end health care coverage for millions of voters who live in GOP-represented districts and states, or cause chaos in health care markets and prompt insurance companies to stop selling policies. So they are considering including provisions in their repeal bill to protect consumers and insurers during the transition period.

Sen. John Thune, R-S.D., a member of the GOP Senate leadership, said that could include money to temporarily continue helping people afford to buy coverage and language letting the Department of Health and Human Services help stabilize insurance markets.
