Former White House senior advisor Karl Rove appeared on "Your World with Neil Cavuto" Friday where he said gun control legislation, particularly a background check bill depends heavily on President Trump.

"If the president backs a background check bill and he takes with him Senator McConnell, who would endeavor to make certain that that bill has enough support that it's written in such a way that it can get 60 votes in the Senate, then it can happen," Rove said.

Rove also factored in the public's support on the issue.

"Public polls support for universal background checks and granted that's an amorphous title, that's not a bill, that's not the detail that's a title. But if you look at the support for that concept it is up there in 90 percent and almost 90 percent among Republicans," Rove said.
