Senate Minority Leader Chuck Schumer criticized President Trump for not checking in with Congressional leaders before ordering a strike to kill Iranian general Qassem Soleimani.

The New York Democrat said 'the lack of advanced consultation and transparency with Congress can lead to hasty and ill-considered decisions.'

'When the security of the nation is at stake, decisions must not be made in a vacuum,' Schumer said.

Talking to Congress, Schumer argued, would allow a president 'to get an outside view to prevent groupthink and rash action.'

'The administration did not consult in this case, and I fear that those very serious questions have not been answered and may not be fully considered,' Schumer said.

Schumer's comments come after Trump had retweeted a tweet that said Schumer wasn't given a heads up 'for pretty much the same reason' Iranians weren't warned of the strike.

The original tweet was written by Dinesh D'Souza, a right-wing filmmaker and provocateur and linked to a breaking news alert that said Schumer 'was not given advance notice of the airstrikes in Baghdad.'

Senate Minority Leader Chuck Schumer, the body's top Democrat, wasn't informed of the administration's plan to strike a top Iranian general Thursday

Conservative filmmaker Dinesh D'Souza responded to a breaking news alert saying Chuck Schumer hadn't known about the strike in advance by saying, 'Neither were the Iranians and for pretty much the same reason'

President Trump then retweeted Dinesh D'Souza's tweet. Trump has only addressed the attack on the top Iranian official using his Twitter account, though is expected to appear at a campaign event later Friday

Schumer and other top Democrats were left out of the loop, while Senate Majority Leader Mitch McConnell hasn't said whether he was clued in.

McConnell, the Senate's top Republican, is also due to speak on the Senate floor Friday, and will do so before Schumer.

Traditionally, there are eight members of Congress the White House would brief on the most classified matters.

Nicknamed the 'Gang of Eight,' they currently consist of McConnell, Schumer, House Speaker Nancy Pelosi, House Minority Leader Kevin McCarthy, Senate Intelligence Committee leaders Richard Burr and Mark Warner and House Intelligence Committee heads Adam Schiff and Devin Nunes.

Schumer pointed to these exact members in his floor speech Friday.

'I'm a member of he Gang of Eight, which is typically briefed in advance of operations of this level of significance.'

It was apparent immediately after the attack that some of the Gang of Eight hadn't been read in.

A statement from House Speaker Nancy Pelosi from Thursday night read, 'this action was taken without the consultation of the Congress.'

And Schiff tweeted Thursday night that while Soleimani was 'responsible for unthinkable violence,' he noted that 'Congress didn't authorize' the strike.

Sen. Lindsey Graham said on Fox News Channel Friday morning that he was told about the plans when he made a trip to Florida to visit with the president earlier this week.

'I was briefed about the potential operation when I was down in Florida,' Graham revealed during a phone interview on Fox News Channel Friday morning. 'I appreciate being brought into the orbit.'

A spokesperson for Graham hasn't clarified whether Graham learned of the plans during his golf game with the commander-in-chief Monday or Tuesday, after the U.S. embassy in Baghdad was ambushed by pro-Iranian protesters.

Trump has used only Twitter to communicate to the American people on the heels of the strike that killed Soleimani and tossed the Middle East into chaos.

The pool of reporters who follow the president made it as far as just outside the perimeter of Trump's Florida Mar-a-Lago estate before being taken back to their hotel.

Trump does have one event on his schedule today, a 5 p.m. 'Evangelicals for Trump' campaign rally at a church in Miami.
