President Donald Trump engaged in yet another bout of contentious back-and-forth with CNN correspondent Jim Acosta, who the president again dismissed as 'fake news' during a clash over immigration.

Trump called on Acosta, who had his credentials yanked by angry White House staffers following an earlier confrontation where the White House accused him of refusing to relinquish the microphone.

This time, Trump sounded off when Acosta asked a long question about immigration, following Trump's decision to go around Congress and declare an 'emergency' to secure $8 billion in funding.

'I wonder if you could comment on this disconnect that we seem to have in the country where you are presenting information about what's happening at the border, calling it an invasion, talking about women with duct tape over their mouths and so on, and yet there is a lot of reporting out there, a lot of crime data out there's a lot of Department of Homeland Security Data out there that shows border crossings at a near record low,' Acosta asked the president.

'What do you say to critics who say that you are creating a national emergency? That you’re concocting a national emergency here to get your wall,' CNN's Jim Acosta asked Trump

'That's because of us,' Trump interjected,' while Acosta kept talking.

Excuse me,' Trump continued, as the two talked over each other. 'It's still massive numbers of crossings.'

Acosta continued, pointing him to statistics that undocumented immigrants commit crimes at lower levels than native-born Americans.

Trump told Acosta: 'You have an agenda. You're CNN. You're fake news'

'Sit down! You get one question!' Trump told Brian Kerem of Playboy magazine

'You don't really believe that stat,' Trump said. 'Do you really believe that stat? Take a look at our federal prisons,' said Trump, as Acosta kept going.

'I believe in facts and statistics,' said Acosta, as the clash grew nearer.

'Any more? Quick, lets go,' Trump said, motioning with his hand.

Then Acosta got to his question. 'What do you say to critics who say that you are creating a national emergency? That you're concocting a national emergency here to get your wall.'

The president shot back by pointing to the 'angel moms' that had been invited to the event, bearing pictures of their children slain by illegal immigrants in an emotional appeal Trump hoped to harness to back up his border wall.

Trump jumped in. 'Ask the Angel moms. You think I'm creating something? Ask these incredible women who lost their daughters and their sons, Okay?' the president told Acosta, as one of the women stood up. 'Because your question is a very political question,' the president claimed.

Then he grew fed up with his questioner: 'Because your question is a very political question because you have an agenda. You're CNN. You're fake news,' Trump scolded.

'The numbers that you gave are wrong,' Trump told him. Take a look at our federal prison population. See how many of them, percentage wise, are illegal aliens. Go ahead and see.

The libertarian Cato Institute examined the issue by looking at Texas, as the Washington Post reported, finding that native born Americans committed considerably more crimes than illegal immigrants. Legal immigrants committed even fewer on a per capita basis.

In keeping with new rules the White House adopted, Acosta relinquished the microphone, after Trump refused his request for a follow up.

Playboy reporter Brian Kerem picked up the effort, asking Trump where he gets his numbers, and pointing to federal statistics showing a decrease in border crossings and in violence.

'No no,' Trump scolded. 'You get one.'

'Sit down! You get one question!' Trump thundered when Kerem tried for a second effort.

'I get my numbers from a lot of sources,' Trump said, 'like Homeland Security primarily,' saying the numbers were 'a disaster.'

'I use many stats, but I also use homeland security. Next question,' Trump finished.
