WASHINGTON – President Donald Trump Thursday tweeted an edited video of House Speaker Nancy Pelosi Thursday night designed to make it look like she was stuttering through a news conference from earlier in the day. That video came hours after a separate altered video was spreading online that slowed down Pelosi's words to make her speech appeared slurred.

The president tweeted the Fox Business clip from the Lou Dobbs show, where Fox Business political analyst Ed Rollins said he thought the House speaker is getting "worn down."

Hillary Clinton, Trump's 2016 Democratic rival, bashed the president's tweet during remarks in Texas at the Harris County Democratic Party's annual JRR luncheon on Friday.

"The president and his cronies have been running around spreading a doctored video of Nancy Pelosi," Clinton said. "Now it is sexist trash. But it is also a sign that Trump is running scared."

Pelosi: Trump is 'crying out' for impeachment but House Democrats are not on that path for now

A three-minute video from Pelosi's Wednesday remarks at the Center for American Progress conference was manipulated so her words sounded slurred and garbled. The video, which Friday morning has 2.4 million views on Facebook and has been shared 47,000 times on that platform, was posted by a group called Politics WatchDog. The video has also made its way onto Twitter and was on YouTube, but has since been removed from that site.

During that event Pelosi repeated her accusation that Trump is engaged in "a cover-up" and indicated that it may be an impeachable offense.

The edited CAP video was slowed to about 75% of its original speed, according to the Washington Post, which first reported on the distorted video. The pitch has also been altered after it was slowed down to make it sound more like Pelosi's actual voice.

Hany Farid, a computer-science professor and digital-forensics expert at University of California, Berkeley, told the Post that there was "no question" the video had been altered and that "it's striking that such a simple manipulation can be so effective and believable to some."

'He wants to be impeached': The war of words between Democrats and the White House

Pelosi and Trump have traded barbs over the past several days after infrastructure funding talks fell apart once the president conditioned further negotiations with Congress on the ending all congressional probes into him, his administration and his finances.

The House speaker has accused the president of being engaged in a "cover-up," adding that he threw a "temper tantrum" at the infrastructure meeting. She has since expressed concern for Trump's and nation's "well-being." Trump on Thursday called Pelosi a "mess." The president also derided her as "crazy" and said she is "disintegrating."
