Facebook and Twitter have refused to take down a video posted by President Donald Trump that was edited to make it appear that House Speaker Nancy Pelosi ripped up his speech when the president was saluting a Tuskegee airman during the State of the Union rather than at the end of his address.

The video intersperses Pelosi tearing the speech again and again following other big moments from Trump's address.

Trump's campaign says the video is a parody. But Pelosi's office had demanded the video, titled “Powerful American stories ripped to shreds by Nancy Pelosi,” be removed from both social media platforms. Trump tweeted the video Thursday evening to his more than 72 million followers.

The spat became public Friday when Pelosi’s deputy chief of staff Drew Hammill tweeted: “The latest fake video of Speaker Pelosi is deliberately designed to mislead and lie to the American people, and every day that these platforms refuse to take it down is another reminder that they care more about their shareholders’ interests than the public’s interests.”

“The American people know that the president has no qualms about lying to them – but it is a shame to see Twitter and Facebook, sources of news for millions, do the same," he continued.

Facebook said the Trump video does not violate its policy on manipulated video. Twitter said the video does not violate its current rules. New rules on altered videos are slated to take effect on March 5.

The video had been viewed 2.1 million times in less than 24 hours, reaching nearly 5 million people, Trump campaign spokesman Tim Murtaugh said.

“If Nancy Pelosi fears images of her ripping up the speech, perhaps she shouldn’t have ripped up the speech,” he told USA TODAY.

Video clips deceptively altered to discredit or embarrass political figures or to mislead voters are a growing problem on social media platforms, which are increasingly playing a central role in American political life. This new wave of dirty political tricks is raising broad concerns about the role of digital manipulation in swaying voter sentiment in U.S. elections.

Tech giants have been wrestling with how to combat disinformation that seeks to deceive and sway voters after Russian interference and the spread of fabricated news stories influenced public opinion during the 2016 presidential election. Manipulated video is expected to increase sharply in the months before the November election.

The state of the union between Democrats and social media companies is fraying.

House Democrats including Rep. David Cicilline, D-R.I., to Rep. Ro Khanna, D-Calif., complained loudly on Twitter, calling on the social media company to remove the Trump video.

“Social media platforms are a place where people come for news & information. They need to have certain standards,” Khanna tweeted. “Falsity has never been part of our 1st Amendment tradition.”

Rep. Veronica Escobar, D-Texas, aimed her comment directly at Twitter CEO Jack Dorsey: "Show your commitment to cut down on the misinformation corroding our nation and take down this fake video."

Open season on Facebook: Top Democrats Joe Biden and Nancy Pelosi take on Facebook, Mark Zuckerberg

'Shameful behavior': Nancy Pelosi isn't accepting Facebook's friend request

Social media companies are taking a lot of flak from leading Democrats, who've grown more openly hostile in recent weeks.

Last month Joe Biden ramped up the Democrats' open season on Facebook and its CEO, Mark Zuckerberg, during an interview with the New York Times.

"I've never been a fan of Facebook," the former vice president said. "I've never been a big Zuckerberg fan. I think he's a real problem."

Biden's comments followed sharp words from Pelosi who, in response to a question about Facebook's power, said: “I think what they have said very blatantly, very clearly is that they intend to be accomplices for misleading the American people with money from God knows where."
