President Donald Trump son-in-law and senior White House adviser Jared Kushner said Monday that he "did not collude" with Russia and had roughly four meetings with Russian officials during the 2016 campaign and presidential transition.

In a written statement released ahead of his appearance before lawmakers in closed-door sessions, Kushner said his initial security clearance form had been submitted prematurely in error and had omitted all foreign contacts.

"I did not collude, nor know of anyone else in the campaign who colluded, with any foreign government," Kushner said.
