House Majority Leader Kevin McCarthy is calling for Twitter to ban an independent congressional candidate for making sexist slurs against first lady Melania Trump.

Mark Roberts, who is challenging Oregon Republican Rep. Greg Walden for his seat, was responding to a tweet from Turning Point USA founder Charley Kirk, who pointed out that the first lady has a much smaller staff than her predecessor Michelle Obama. Kirk said there are only five White House staffers as opposed to the 44 who worked for Obama.

Roberts, whose website says he is running as a “independent conservative” responded to Kirk’s tweet by saying the first lady “works by the hour” with the hashtags “#thinkdirty” and “#hoebag.”

Did you know the First Lady works by the hour? #thinkdirty #hoebag

In response, McCarthy called on Roberts to be banned from Twitter, calling the attack “disgraceful.”

“Comments like these have no business on any platform,” the California Republican said. “This account should be banned ASAP.”

Democrat Jamie McLeod-Skinner is also running against Walden and Roberts.

Inside Elections with Nathan L. Gonzales rates Oregon’s 2nd District Solid Republican. President Donald Trump carried the seat by 20 points in 2016.
