President Trump fired up a gathering of young conservatives on Tuesday — lashing out at “the Squad” and Robert Mueller, and repeating charges that illegal immigrants voted multiple times in California and other states.

The president singled out Rep. Rashida Tlaib of Michigan, calling her “vicious” and ”a crazed lunatic,” referring to a video showing Tlaib shouting and struggling as security marched her out for heckling Trump during a speech in Detroit in August 2016, more than two years before she was elected.

“I watched this morning this Tlaib, this Tlaib from Michigan. She’s vicious, she’s crazed, she’s screaming. This was not a sane person folks. This is what we’re up against,” Trump said at Turning Point USA’s Teen Student Action Summit 2019 at DC’s Marriott Marquis.

“There’s no way she stands for the values of the people of Michigan.”

He also repeated claims that Rep. Alexandria Ocasio-Cortez called America “garbage,” and that other members of the Squad, which also includes Ilhan Omar of Minnesota and Ayanna Pressley of Massachusetts, had referred to “evil Jews.”

The freshmen lawmakers, all women of color, and their backers have said there was no evidence to support those allegations, and assert that the president had taken other comments they had made out of context.

Trump also gave the four a new nickname — “AOC plus 3.”

“Not that AOC is a bargain, she’s not. At some point I got more on AOC. I got a lot on AOC, sometime I’ll tell you,” he said.

The crowd of young conservative teens — many sporting red MAGA caps — cheered and chanted “USA! USA!,” “Four more years!” and “One Squad under God,” a reference to a phrase from a recent Trump campaign video.

The president also charged that there were 20 or so other Democrats in Congress who were “worse” than the Squad.

“They have a big problem. They have others than these four. I can name another 20 that are worse. They’re Democrats. At some point we will be naming them if you don’t mind,” he told the crowd, members of a nationwide group organized by conservative activist Charlie Kirk.

Trump also targeted Mueller a day before the special counsel’s testimony to Congress, repeating his description of the probe as a “witch hunt.”

And he claimed that illegal immigrants vote over and over again in California and other states, a charge state election officials and others have repeatedly said was untrue.

“Illegals vote. Those numbers in California and a number of other states? Don’t believe them, they’re rigged. They vote many times, not twice, not three times. It’s like a circle, they go back,” he contended, saying that sometimes they change their clothes to disguise themselves.

During the campaign-style rally, which was preceded by a video detailing Trump’s rise from Queens to the White House, the president also touted progress on the wall on the southern border, lashed out at “fake news,” NATO and the EU but praised new British Prime Minister Boris Johnson.

“He’s a really good man. He’s tough and he’s smart. They’re saying Britain Trump. They call him Britain’s Trump. That’s a good thing. They like me over there,” he said.
