In his latest attack on news media, the US president on Sunday tweeted a bizarre video of him attacking a man whose head was replaced with a CNN logo
Thousands of angry protesters rallied in various cities across the US, chanting anti-Donald Trump slogans, to urge Congress to impeach President Donald Trump.
Organisers say they believe the president has violated the US Constitution and obstructed justice.

On Sunday, Trump tweeted a video of himself at a pro-wrestling event throwing to the floor a man with a CNN logo for a head.
In the 28-second video, Trump, dressed in a suit, is seen knocking down another man in a suit who is standing next to a wrestling ring. Trump then pummels the man, whose face is covered by the CNN logo, repeatedly over the head.
At the end of the video, a fake CNN logo appears in the lower right corner of the screen with the words "FNN: Fraud News Network."
Last week, 3 CNN journalists resigned after an article on Russia-Trump relations was retracted by the network. Report author Thomas Frank and two senior CNN Investigations Unit figures Eric Lichtblau and Lex Haris resigned over the story.
CNN said the article was taken down since “some standard editorial processes were not followed when the article was published”.
Trump took this opportunity to attack CNN and the media in general.
He wrote on Twitter: “Fake News CNN is looking at big management changes now that they got caught falsely pushing their phony Russian stories. Ratings way down!”
Donald Trump attacked MSNBC morning show co-host Mika by calling her "dumb as a rock".
His tweet came just a day after he took to Twitter last week to call Brzezinski "low IQ" and "crazy".
After Brzezinski questioned Trump's management style, he tweeted: "I heard poorly rated @Morning_Joe speaks badly of me (don’t watch anymore)."
"Then how come low I.Q. Crazy Mika, along with Psycho Joe, came to Mar-a-Lago 3 nights in a row around New Year’s Eve, and insisted on joining me. She was bleeding badly from a face-lift. I said no!"
The feud between Trump and Kelly started on August 6, 2015, at the first Republican presidential debate. In a question directed at Trump, Kelly said, “You’ve called women you don’t like fat pigs, dogs, slobs and disgusting animals.”
After the debate, Trump took to Twitter, where he wrote, “Wow, @megynkelly really bombed tonight. People are going wild on twitter! Funny to watch.”
Days later, Trump said Kelly had "blood coming out of her eyes, blood coming out of her wherever".
Former Hewlett Packard CEO Carly Fiorina, who was a candidate in the 2016 Republican presidential primary, is no stranger to Trump’s sexist comments.
In September 2015, Trump mocked Fiorina’s appearance.
"Look at that face! ... Would anyone vote for that?" Trump was quoted asking while watching Fiorina on the news. "I mean, she's a woman, and I'm not [supposed to] say bad things, but really, folks, come on. Are we serious?"
