WASHINGTON — As part of his frenzied attempt to cling to power, President Donald J. Trump reached out repeatedly to members of Congress on Jan. 6 both before and during the siege of the Capitol, according to White House call logs and evidence gathered by the House committee investigating the attack.
The logs, reported earlier by The Washington Post and CBS and authenticated by The New York Times, indicated that Mr. Trump had called Republican members of Congress, including Senator Mitch McConnell of Kentucky, Senator Josh Hawley of Missouri and Representative Jim Jordan of Ohio, as he sought to pressure Vice President Mike Pence to reject electoral votes from several states.
But the logs also have a large gap with no record of calls by Mr. Trump from critical hours when investigators know that he was making them. The call logs were among documents turned over by the National Archives to the House committee examining the Jan. 6 attack last year on the Capitol.
The New York Times reported last month that the committee had discovered gaps in official White House telephone logs from the day of the riot. The Washington Post and CBS reported Tuesday that a gap in the phone logs amounted to seven hours and 37 minutes, including the period when the building was being assaulted.
Investigators have not uncovered evidence that any of the call logs were tampered with or deleted. It is well known that Mr. Trump routinely used his personal cellphone, and those of his aides, to talk with other aides, congressional allies and outside confidants, bypassing the normal channels of presidential communication and possibly explaining why the calls were not logged.
The logs appear to have captured calls that were routed through the White House switchboard. Three former officials who worked under Mr. Trump said that he mostly used the switchboard operator for outgoing calls when he was in the residence. He would occasionally use it from the Oval Office, the former officials said, but more often he would make calls through the assistants sitting outside the office, as well as from his cellphone or an aide’s cellphone. The assistants were supposed to keep records of the calls, but officials said the record-keeping was not thorough.
People trying to reach Mr. Trump sometimes called the cellphone of Dan Scavino Jr., the former deputy chief of staff and omnipresent aide, one of the former officials said. (The House committee investigating the attack recommended Monday evening that Mr. Scavino be charged with criminal contempt of Congress for refusing to cooperate with a subpoena from the panel.)
But the call logs nevertheless show how personally involved Mr. Trump was in his last-ditch attempt to stay in office.
One of the calls made by Mr. Trump on Jan. 6, 2021 — at 9:16 a.m. — was to Mitch McConnell of Kentucky, the Senate’s top Republican, who refused to go along with Mr. Trump’s pressure campaign. Mr. Trump checked with the White House switchboard operator at 10:40 a.m. to make sure a message had been left for Mr. McConnell.
Mr. McConnell declined to return the president’s calls, he told reporters on Tuesday.
“The last time I spoke to the president was the day after the Electoral College declared President Biden the winner,” Mr. McConnell said. “I publicly congratulated President Biden on his victory and received a phone call after that from President Trump and that’s the last time we’ve spoke.”
The logs also show Mr. Trump reached out on the morning of Jan. 6 to Mr. Jordan, who had been among those members of Congress organizing objections to Mr. Biden’s election on the House floor.
The logs show Mr. Trump and Mr. Jordan spoke from 9:24 a.m. to 9:34 a.m. Mr. Jordan has acknowledged speaking with Mr. Trump on Jan. 6, though he has said he cannot remember how many times they spoke that day or when the calls occurred.
Mr. Trump called Mr. Hawley at 9:39 a.m., and Mr. Hawley returned his phone call. A spokesman for Mr. Hawley said Tuesday that the two men did not connect and did not speak until March. Mr. Hawley had been the first senator to announce he would object to President Biden’s victory, and continued his objections even after rioters stormed the building and other senators backed off the plan.
The logs also show that Mr. Trump spoke from 11:04 a.m. to 11:06 a.m. with former Senator David Perdue, Republican of Georgia, who had recently lost his re-election campaign to Senator Jon Ossoff.
A spokesman for Senator Bill Hagerty, Republican of Tennessee, confirmed he had called Mr. Trump on Jan. 6 but said they did not connect. Mr. Hagerty declined to comment.
Despite the lack of call records from the White House, the committee has learned that Mr. Trump spoke on the phone with other Republican lawmakers on the morning of Jan. 6.
For instance, Mr. Trump mistakenly called the phone of Senator Mike Lee, Republican of Utah, thinking it was the number of Senator Tommy Tuberville, Republican of Alabama. Mr. Lee then passed the phone to Mr. Tuberville, who said he had spoken to Mr. Trump for less than 10 minutes as rioters were breaking into the building.
Capitol Riot’s Aftermath: Key Developments
Trump’s tweet. Weeks before the Jan 6 attack, President Donald J. Trump sent a tweet that ended “Be there, will be wild!” Federal prosecutors and congressional investigators have gathered growing evidence of how this tweet was a crucial call to action for militants in the riot.
Judge says Trump likely committed crimes. In a court filing in a civil case, the Jan. 6 House committee laid out the crimes it believed Mr. Trump might have committed. The federal judge assigned to the case ruled that Mr. Trump most likely committed felonies in trying to overturn the 2020 election.
Virginia Thomas’s text messages. In the weeks before the Capitol riot, Virginia Thomas, the wife of Supreme Court Justice Clarence Thomas, sent several texts imploring Mark Meadows, President Trump’s chief of staff, to take steps to overturn the election. The Jan. 6 House committee is likely to seek an interview with Ms. Thomas, said those familiar with the matter.
Contempt charges. The Jan. 6 House committee voted to recommend criminal contempt of Congress charges against Peter Navarro, a former White House adviser, and Dan Scavino Jr., a former deputy chief of staff, for refusing to comply with its subpoenas.
The president also fielded a call from Representative Kevin McCarthy of California, the top House Republican, who told Mr. Trump that people were breaking into his office on Capitol Hill.
During that call, Mr. Trump was said to have sided with the rioters, telling the top House Republicans that members of the mob who had stormed the Capitol were “more upset about the election than you are.”
Rudolph W. Giuliani, Mr. Trump’s personal lawyer, was also calling lawmakers that day and continued to do so even after rioters laid siege to the building. In an evening phone call, he made clear that the effort to fight the result of the election was still alive even after the riot.
“Senator Tuberville, or I should say Coach Tuberville, this is Rudy Giuliani, the president’s lawyer,” Mr. Giuliani said in a voice mail message intended for Mr. Tuberville, but mistakenly left on Mr. Lee’s phone. “I’m calling you because I want to discuss with you how they’re trying to rush this hearing and how we need you, our Republican friends, to try to just slow it down.”
The news of the call logs came the same day that the White House said President Biden would not extend executive privilege to cover any testimony to the committee by Ivanka Trump and Jared Kushner, Mr. Trump’s daughter and son-in-law, who worked as his advisers.
“The president has spoken to the fact that Jan. 6 was one of the darkest days in our country’s history, and that we must have a full accounting of what happened to ensure that it never occurs again,” said Kate Bedingfield, a White House spokeswoman. “And he’s been quite clear that they posed a unique threat to our democracy and that the constitutional protections of executive privilege should not be used to shield, from Congress or the public, information about an attack on the Constitution itself.”
Mr. Kushner is scheduled to testify before the committee this week, while Ms. Trump has been negotiating the terms of her potential cooperation.
