WASHINGTON — Attorney General Jeff Sessions quoted Kanye West, whacked liberal “snowflakes” and even inspired a vintage “Lock her up!” chant during an appearance before a conference of conservative high school students Tuesday.

Sessions was speaking at Turning Point USA’s High School Leadership Conference and kicked off his speech by thanking some of the organizers, including Candace Owens, a conservative activist who serves as the group’s director of urban engagement.

“I know a lot of people love the way Candace thinks,” Sessions said. “Kanye West once said — she’s got the same kind of ‘Dragon Energy’ that he said the president had.”

“That is a good description of President Donald Trump. The man has extraordinary energy,” Sessions added, slinging a compliment at his boss, who has hammered the attorney general publicly for recusing himself from the Russia investigation.

Most of Sessions’ speech was dedicated to the premise that “freedom of thought and speech on the American campus are under attack.”

He complained how Black Lives Matter had tried to shut down an American Civil Liberties Union event at William & Mary in September 2017.

“They chanted ‘Liberalism is white supremacy’ and ‘ACLU, you protect Hitler too.’”

“The ACLU doesn’t mind calling other people names — but I bet they didn’t like that,” Sessions said.

He referenced other incidents, like a protest at Middlebury College that resulted in a liberal professor being injured after protesters swarmed a planned event with libertarian author Charles Murray.

“And although the protesters were a group of leftists, it was the liberal professor who ended up in the hospital,” Sessions scoffed. “She said she ‘feared for her life.’ This was at Middlebury College!”

Sessions said the schools were “complicit in this effort to prevent genuine debate and engagement with ideas.”

“Through trigger warnings about microaggressions, cry closets, safe spaces, optional exams, therapy goats and grade inflation, too many schools are coddling our young people and actively preventing them from scrutinizing the validity of their beliefs,” the attorney general said. “That is the exact opposite of what they’re supposed to do.”

“After the 2016 election, for example, they held a ‘cry-in’ at Cornell,” Sessions continued. “I hope they had plenty of tissues.”

Sessions noted how therapy dogs were brought on campus at the University of Kansas and Play-Doh was provided to students at “the great” University of Michigan. Students at Tufts, Sessions added, were “encouraged to draw out their feelings.”

“Give me a break,” Sessions said.

Acknowledging the raucous crowd, Sessions said the conservative youngsters were better than that.

“You’re going to stand up and defend yourselves. Go get ‘em! Go get ‘em!” the attorney general cheered.

This inspired the audience to fire back a “Lock her up!”

“Lock her up,” Sessions repeated with a laugh. “I heard that a long time on the last campaign.”

Getting back to the meat of his speech, he used another favorite term of conservatives.

“Rather than molding a generation of mature and well-informed adults, some schools are doing everything they can to create a generation of sanctimonious, sensitive, supercilious snowflakes,” Sessions said.

“That is a disservice to their students and a disservice to this nation,” he added.
