House Minority Whip Steve Scalise said Rep. Alexandria Ocasio-Cortez should "stand up" to some of her more "radical" followers.

Scalise (R-La.) abruptly halted a Twitter debate with Ocasio-Cortez (D-N.Y.) on Sunday after several of her supporters made references to the June 2017 shooting in which Scalise and three other people were shot by a left-wing activist.

Prior to the Twitter comments, Scalise and Ocasio-Cortez had been debating the Democrat’s proposal for enacting a tax rate of up to 70 percent on income. Scalise had called for letting Americans “keep more of their own hard-earned money.”

After several Ocasio-Cortez supporters referenced the shooting -- including comments like "snip his a**" and "kick his cane" -- Scalise ended the online discussion, tweeting that he would be happy to continue the debate on the House floor, as it was unproductive to engage with the freshman congresswoman's "radical followers."

"I'd like to see her stand up to this," Scalise said on "Fox & Friends" Monday. "Everybody ought to stand up to this kind of discussion."

He said he is always open to an honest policy debate, which he said is what the First Amendment is "all about."

"But you shouldn't threaten people. And if you've got to threaten people to make your point, you've already lost."

In a "60 Minutes" interview with Anderson Cooper, Ocasio-Cortez said the revenue from the tax increase would fund a “Green New Deal,” with a goal of eliminating fossil fuel use in 12 years.

"What is the problem with trying to push our technological capacities to the furthest extent possible?" she asked, arguing the rich must pay their "fair share."

She said the 60 to 70 percent top tax rate would apply to income earned beyond $10 million. Ocasio-Cortez said she's proud to be labeled a "radical" and responded "yeah, no question" when asked whether President Trump is a racist.
