President Donald Trump’s claims that his election is rigged were not based on facts, but rather “falsehoods” that have been debunked in recent weeks, the top Democrat on the Senate Intelligence Committee said Friday.

Sen. Mark Warner (D-Va.) said the president is “in a state of denial” about the extent of voter fraud and that his administration has repeatedly sought to cast doubt on the legitimacy of the election.

“The president is in a state to deny the legitimacy and the legitimacy is that he lost the election,” Warner told MSNBC’s Rachel Maddow.

“We know that we are not going to get the truth.

We are going to fight the president for as long as it takes.”

The president has repeatedly claimed that millions of people voted illegally during the 2016 presidential election, despite overwhelming evidence to the contrary.

But a majority of the nation’s political parties have long been clear that the election was “not fair” and that millions voted illegally.

The president also dismissed concerns about the legitimacy in an interview with NBC News on Friday, telling host Savannah Guthrie that he had no proof of any voter fraud.

“There’s nothing to it.

There’s no evidence of any of that,” Trump said.

“And you’re going to have a lot of people that are going say, ‘Oh, my God, I have a million votes, but I can’t even figure out who voted for me.'”

“The media and other people are going, ‘Well, they’re not going say anything because that’s not a legitimate process, but they’re going, you know, they want to keep the election ‘fair,'” Warner added.

“Well, no, we’re going on the side of the people that we know are honest, who are voting, and we’re saying, ‘That’s not fair, you’re not supposed to vote.

That’s not right.'”

Trump’s claim that millions illegally voted in November’s election has been debunked repeatedly.

A CNN analysis of official election results from several states found that nearly 7 million people cast ballots in November, a rate far below the nearly 11 million that the president himself predicted would cast ballots.

A report by the nonpartisan Brennan Center for Justice found that the actual number of votes cast is much lower, at around 1.2 million.

Trump has repeatedly dismissed the report as “fake news.”

Trump’s election claims have also been debunked by the American Civil Liberties Union, which said in a letter Friday that the claim that Trump “has been elected by a rigged system of fraud and intimidation is false.”

The group, which has endorsed Hillary Clinton, wrote that there is no evidence that millions or even tens of millions of votes were stolen or cast illegally.

In response to Warner’s comments, the White House issued a statement saying that the administration will continue to vigorously defend the integrity of the electoral process.

“While we have not yet seen the full text of the letter sent by the Brennan Center, we strongly disagree with their characterization of the Brennan report as fake news,” the statement said.
