(CNN) While advisers to Donald Trump and President Barack Obama spar over Russia, the President-elect met with the outgoing homeland security chief Friday.

The sit-down with Secretary Jeh Johnson was announced Friday morning by Trump's spokesman Jason Miller, who did not elaborate on the topics of the meeting. Johnson was spotted entering Trump Tower in New York around 10 a.m.

Obama has been hesitant to directly criticize Trump. He said in an interview that aired late Thursday that he would "take action" and that the conversation around Russia and hacking response should not be a "partisan issue."

"It requires us not to re-litigate the election, it requires us not to point fingers, it requires us to just say, here's what happened, let's be honest about it, and let's not use it as a political football but let's figure out how to prevent it from happening in the future," Obama told NPR.
