Anticipation is growing that Attorney General William Barr might provide an update to lawmakers on Sunday, as no briefing was held on Saturday. He was spotted arriving at the Department of Justice offices around 10 a.m., and sources indicate that Barr could send a summary to Congress by the end of the day.

How much of the report will be released and how soon it will make its way to the public are top questions for both lawmakers and observers. Members of Congress speculated Sunday morning on the contents of the report and its meaning and honed their arguments in advance of any release of information.

"The report should go public in its entirety and see where the chips fall," Nadler said on "Fox News Sunday," adding that he would "absolutely" take the matter all the way to the Supreme Court if necessary.

Nadler characterized the full report as critical to Congress's ability to conduct proper oversight.

"Congress must get all the information and the evidence that the Department of Justice may have in order to exercise our function of being able to hold the president accountable," he said on NBC. "If we don’t do that, if we can’t do that, the president is effectively above the law."

He also argued on "Fox News Sunday" that it would be "equivalent to a cover-up" if the Department of Justice refused to release the underlying information behind Mueller's report under the reasoning that President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE can't be indicted.

Nadler further asserted that Trump should not be able to assert executive privilege to shield certain parts of the report from going public, citing a 1974 Supreme Court ruling that compelled then-President Richard Nixon to comply with a request for tape recordings.

As Democrats prepare for a fight should the White House or Department of Justice resist making the report public, Republicans were quick to declare the conclusion of the investigation a win for Trump even as they await the full document.

"That is the core finding at least in what we’re seeing so far," he added, cautioning that lawmakers have not yet seen the special counsel's findings.

"This has consumed two years of the American people's time, and we need to have full transparency," Cruz said on "State of the Union" on CNN. "We need to know the special counsel's conclusions."

Rubio said on NBC's "Meet the Press" that he'd like to see the underlying surveillance applications that factored into the start of the investigation of Russian interference and collusion as well.

"I would suspect that at the end of the day they are going to release the report," he said. "They’re going to redact intelligence information or classified information, and they’re not going to put things in there about people that is damaging to people that they chose not to prosecute."

Trump, meanwhile, has been uncharacteristically quiet. While he derided the Mueller investigation as a "witch hunt" more than 100 times on Twitter in 2018 alone, the president has yet to comment publicly on the conclusion of the investigation that has served as the backdrop to nearly his entire presidency thus far.

"Good morning, Have a Great Day!" he tweeted early Sunday, breaking his silence on Twitter, which began Friday afternoon.

Trump spent Sunday morning at his golf club in West Palm Beach, Fla., for a second consecutive day. Deputy spokesman Hogan Gidley told reporters that as of Sunday morning, the White House had not been briefed on or received an advance copy of the Mueller report, something Nadler warned against.

"I certainly hope that does not happen, and I certainly do have a problem with that," Nadler said on Fox. "This is an investigation of the White House, of the president, of the people around them for alleged misconduct in various different ways and for subverting the Constitution in various different ways."

It remains unclear if or when Congress would have access to the special counsel's full report. Barr is likely to deliver a summary of Mueller's main findings, but the full document is expected to be scrubbed for classified information and evidence that might be relevant in other ongoing probes.

The special counsel's findings will in many ways dictate the direction Congress chooses to go next.

Republicans have largely expressed a desire to move on from questions about collusion and Trump's involvement, but Democrats have already launched additional investigations into the administration and the president's campaign and business.

Many top Democrats have held their fire on talk of impeachment proceedings, saying they'd prefer to wait for Mueller to conclude his investigation.

Now that the moment has arrived, some Democrats are continuing to take a wait-and-see approach.

Rep. Adam Schiff Adam Bennett SchiffChris Matthews ripped for complimenting Trump's 'true presidential behavior' on Ginsburg Trump casts doubt on Ginsburg statement, wonders if it was written by Schiff, Pelosi or Schumer Top Democrats call for DOJ watchdog to probe Barr over possible 2020 election influence MORE (D-Calif.), one of Trump's most outspoken critics in Congress, said it's "too early" to judge whether impeachment is warranted based on Mueller's report.

Nadler, who as Judiciary chairman would oversee impeachment proceedings, took a similar position.

"It's way too early to talk about impeachment or not," he said. "As I said, our mandate is not to impeach the president or anything like that. Our mandate is to defend the rule of law and to vindicate our constitutional liberties and to buck up the institutions that have been weakened by the attacks of this administration, the institutions that we depend on for our democratic form of government."
