2024 election live updates: Beyonce to join Kamala Harris rally in Houston, ABC News sources say

In a Wednesday social media post, former President Donald Trump suggested that Vice President Kamala Harris criticized him as a "fascist" because she is losing ground in the presidential race.

"She is a Threat to Democracy, and not fit to be President of the United States -- And her Polling so indicates!" Trump fired back at the vice president.

"Now she is increasingly raising her rhetoric, going so far as to call me Adolf Hitler," Trump added.

Trump did not mention why Hitler's name emerged. The New York Times reported this week that the former president allegedly praised Hitler, according to former White House chief of staff John Kelly.

During Wednesday's town hall, moderated by CNN's Anderson Cooper, Vice President Kamala Harris was asked point-blank if she believes former President Donald Trump is a fascist.

The race for the White House is still within the margin of error as a recent poll shows Trump with narrow 2-point lead nationally

"Let me ask you tonight, do you think Donald Trump is a fascist?" Cooper said.

"Yes, I do. Yes, I do. And I also believe that the people who know him best on this subject should be trusted," Harris replied, referencing the recent statements made by John Kelly, Trump's former chief of staff.

Trump lashed out Wednesday at John Kelly following his former chief of staff's accounts that Trump praised Adolph Hitler and denigrated soldiers and veterans.

Trump's former chief of staff says he fits 'fascist' definition and prefers 'dictator approach'

In a lengthy post on Truth Social, Trump claims Kelly, who he labeled a "degenerate" and "tough and dumb," "made up a story out of pure Trump Derangement Syndrome Hatred!"

"The story about the Soldiers was A LIE, as are numerous other stories he told. Even though I shouldn't be wasting my time with him, I always feel it's necessary to hit back in pursuit of THE TRUTH. John Kelly is a LOWLIFE, and a bad General, whose advice in the White House I no longer sought, and told him to MOVE ON!" Trump said.

Robert F. Kennedy Jr. filed an emergency application with the U.S. Supreme Court on Wednesday that seeks to order the Wisconsin Election Commission to cover his name on the swing state's presidential ballot by with stickers.

Previous attempts to remove Kennedy's name from the ballot were rejected by state and federal courts.

Kennedy argues that his 1st and 14th Amendment rights are being violated by keeping his name on the ballot.

It's likely the court will seek a response from the Wisconsin Elections Commission before rendering a decision on whether to intervene in the next 13 days.

Kennedy was running for president as.a Democrat before abandoning that effort to run as an independent instead. He later suspended that campaign and endorsed Trump.
