Kathy Griffin has hit out at Donald Trump after he viciously tore into the hosts of Morning Joe.

The comedian accused the president of 'punching down' after he attacked 'low I.Q. Crazy Mika' and 'Psycho Joe' in Thursday morning tweets for trash talking him on their show - prompting a huge backlash against Trump.

Griffin, who has kept a relatively low profile since she sparked outrage by posting a mock-up of Trump's severed head earlier this month, criticized Trump's tweets and accused him of bullying those less powerful than himself.

'POTUS likes to punch down. Whether it's anchors, US Attorneys, or standup comics. Meanwhile, millions are about to lose health insurance,' Griffin said in her first major Trump post since her public apology four weeks ago.

Earlier on Thursday, the businessman-turned-politician had tweeted about Mika Brzezinski and Joe Scarborough, writing: '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 shocking comments sparked a furious backlash with even lawmakers from his own party reacting to the president's latest headline-grabbing Twitter assault.

'Please just stop. This isn't normal and it's beneath the dignity of your office,' wrote Sen. Ben Sasse, R-Neb., on Twitter. Sen. Lindsey Graham, R-S.C., made a similar comment: 'Mr. President, your tweet was beneath the office and represents what is wrong with American politics, not the greatness of America,' he tweeted.

It is not the first time Griffin has had a run in with the president.

Four weeks ago, the comic was forced to issue a public apology after she posted a picture of herself holding up what appeared to be the severed head of Trump, on Twitter.

She also posted a video of the making of the photo shoot.

Griffin, an outspoken opponent of Trump who was best known for presenting the New Year's Eve countdown with Anderson Cooper on CNN, is seen holding the head, which is slathered in fake blood.

During footage of the shoot, posted on her own official website, Griffin said: 'Tyler and I are not afraid to make images that make noise.'

The resulting backlash saw Griffin's upcoming tour gigs cancelled while CNN announced it had fired Griffin from her annual gig co-hosting its New Year's Eve program with network anchor Anderson Cooper.

'CNN has terminated our agreement with Kathy Griffin to appear on our New Year's Eve program,' the network's PR department tweeted.

REPUBLICANS TURN ON THE PRESIDENT OVER MIKA SLUR Soon after Trump's attacks, lawmakers from his own party began to react to the president's latest headline-grabbing Twitter assault. 'Please just stop. This isn't normal and it's beneath the dignity of your office,' wrote Sen. Ben Sasse, R-Neb., on Twitter. Sen. Lindsey Graham, R-S.C., made a similar comment. 'Mr. President, your tweet was beneath the office and represents what is wrong with American politics, not the greatness of America,' he tweeted. House Speaker Paul Ryan, R-Wis., was asked about the president's tweets during his Thursday press conference. 'Obviously, I don't see that as an appropriate comment,' Ryan said. 'Look, what we're trying to do around here is improve the tone and civility of the debate.' Advertisement

Even former first daughter Chelsea Clinton was quick to express her outrage at Griffin tweeting: 'This is vile and wrong. It is never funny to joke about killing a president.'

At the time, Griffin said that Trump 'broke' her and that 'There's a bunch of old white guys trying to silence me!'

Griffin says she is still getting death threats over the severed head scandal but nothing would stop her mocking Trump.

'This bully, this President, of all people, is gonna come after me?' Griffin said in a press conference, NY Daily reports. 'He picked the wrong redhead.'

Meanwhile, both Brzezinski and Scarborough, who are recently engaged, have chosen to delay that July 4 vacation by one day so they can respond to Trump's tweets on air, Friday.

After Trump's tweets, Brzezinski hit back minutes later on the social media platform, sharing a 'little hands' picture in a throwback to Trump's campaign argument with Sen. Marco Rubio that morphed into a debate about the size of their appendages.

Scarborough let CNN's Jake Tapper do the talking for him. 'This reminds me: how is @FLOTUS's campaign against cyber-bullying going?' the CNN host said in a message that Scarborough retweeted.

At Mar-a-Lago: The Morning Joe hosts did meet with Trump when he was president-elect on New Year's Eve at his Florida resort.

NBC's Peter Alexander reported 10 minutes later that he had asked the First Lady's office about the anti-cyberbullying effort and a 'spox says Melania's "continuing to be thoughtful abt her platform." More announcements TK.'

Later Stephanie Grisham, the first lady's spokeswoman, said: 'As the First Lady has stated publicly, when her husband gets attacked, he will punch back 10 times harder.'

And Deputy White House Press Secretary Sarah Huckabee Sanders forcefully backed up her boss, saying he was in the right for calling Morning Joe's hosts Joe Scarborough and Mika Brzezinski 'psycho' and 'crazy.'

'This is a president who fights fire with fire and certainly will not be allowed to be bullied by a liberal media and the liberal elites within the media or Hollywood or anywhere else,' Huckabee Sanders said Thursday morning on Fox News Channel.

She commented an on-camera briefing later 'it's kind of like we're living in the Twilight Zone.'
