Donald Trump was angry when the Supreme Court rejected his challenge to the results of the 2020 election and did not want people to know he had lost.

A Secret Service agent warned other members about Trump's response in an email obtained by the committee.

It's just fysi. The message was sent in December of 2020. The supreme court denied his law suit. He's angry now.

The House select committee presented new videotaped testimony from Cassidy Hutchinson, a former aide to White House chief of staff MarkMeadows, who witnessed Trump's fury on the day that the Supreme Court rejected his appeal.

The White House hosted a Christmas reception for Hutchinson and Mr. Meadows. The president walked out of the Oval Office and we crossed paths in the colonnade.

The president was angry with the Supreme Court decision.

She could hear Trumpraging about the decision, and how it's wrong, and he wondered why he didn't call more. He was angry at the decision.

Trump said something to the effect of, "I don't want people to know we lost," according to Hutchinson. It's embarrassing. It's time to figure it out We need to find out what's going on. I don't want anyone to know that we lost.

Trump has never conceded the election. According to testimony presented by the committee Thursday, the former president privately accepted his defeat before the Capitol attack.

Gen. Mark Milley said in his testimony that there was a discussion going on in the Oval Office. "And the president says, I think it could have been Secretary of State Mike Pompeo, but he says words to the effect of, 'We need to let that issue go to the next guy,' meaning President Biden."

The former White House director of strategic communications told the committee that after the election he went to the Oval Office to see how the president was doing. He looked at the TV and wondered if he had lost to the effing guy.

The House select committee has given 10 public presentations about the events surrounding the Capitol insurrection.

The committee has used the televised hearings to shine a light on what Liz Cheney, R-Wyo., its co-chair, has called former Trump's "sophisticated seven part plan to overturn the election and prevent the transfer of presidential power."
