Her attack came hours after Booker told Newsweek that if Democrats were able to retake the Senate during November's midterm elections, then Kavanaugh "should be held accountable" were he found "unequivocally" to have lied during his Senate hearings.

“Clearly the FBI was severely constrained in the scope of their investigation in a way that did not honor the courage of the survivors who came forward," Booker said, adding that there were "a number of things that the FBI could have easily investigated to see if he was lying about his past conduct.”

“If there is conclusory evidence that shows unequivocally that he lied to a Senate committee, that is a crime and he should be held accountable for those criminal acts,” Booker told the magazine.

Loesch responded on Twitter, questioning whether Booker's remarks were aimed at helping Republicans remain in control of Congress ahead of the elections.

"Is Cory Booker working with the GOP to help increase voter turnout? Because this is how you increase Republican voter turnout," she wrote.

Booker's office did not immediately respond to a request for comment from The Hill on Loesch's comments.

The New Jersey Democrat is considered to be a possible contender for the 2020 Democratic Party nomination, and has recently attended events in crucial early-primary states such as Iowa.

“We’re not defined by a president who does not believe women,” Booker told a crowd of Iowa Democrats on Saturday. “This is not a time to curl up. It is not a time to shut up. It is not a time to give up. It is a time to get up, to rise up, to speak up."
