Academy Award-winning actor James Woods is warning fellow conservatives to ignore freshman New York Rep. Alexandria Ocasio-Cortez “at your peril.”

“This is the most dangerous person in America right now,” the “Videodrome” star tweeted Thursday, a day after Ocasio-Cortez gave her first speech on the floor of the House, where she slammed President Trump over the ongoing partial government shutdown.

”It is not normal to hold 800,000 workers’ paychecks hostage. It is not normal to shut down the government when we don’t get what we want,” she said in her address.

In a Twitter rant in which he took aim at House Speaker Nancy Pelosi, Woods, 71, referenced a Fox News report in a since-deleted post, asking the 29-year-old Democratic congresswoman to “demonstrate your expertise in ‘running the train,’” Newsweek reported.

Dan Bongino’s opinion piece provides the numbers of Ocasio-Cortez’s tax plan and claims she has “economic ignorance” and assumes Americans will think: “Hey, it’s not gonna affect me — it’s just going to screw people who make $10 million or more.”

The actor followed up his deleted tweet with an explanation of where the urban idiom “run the train” came from.

“I’m six days into term, and you already used up your ammo,” Ocasio-Cortez said in a Fox News piece tweeted by the actor. “So enjoy being exhausted for the next two years while we run train on the progressive agenda.”

Ocasio-Cortez has 2.4 million followers on Twitter — to Woods’ 1.93 million — and 1.8 million followers on Instagram.
