President Donald Trump is faulting his predecessor’s handling of Russia’s meddling in the 2016 election.

Trump tells Fox News contributor Pete Hegseth in an interview set to air Sunday that he “just heard today for the first time” that former President Barack Obama “knew about Russia a long time before the election, and he did nothing about it.”

He says Obama “should have done something about it.”

Trump appeared to be referring to a Washington Post story about the Obama administration’s attempts to address Russia’s influence attempts.

Obama ordered a review of Russia’s actions and imposed new sanctions after the election.

Trump has acknowledged that Russia likely tried to interfere in the election, but has denounced investigations into possible Russian collusion with his campaign as a “witch hunt.”
