President Trump claimed Tuesday that his predecessor, Barack Obama, was aware of Russia's attempts to meddle in U.S. affairs starting in 2014, and did nothing.

"According to report just out, President Obama knew about Russian interference 3 years ago but he didn't want to anger Russia!" Trump tweeted Tuesday morning.

Trump didn't say what report he was citing, but Politico reported Monday that Obama's team had "multiple warnings" in 2014 and 2016 that Russia was looking to somehow disrupt the U.S. political system.

Trump has previously chided Obama for learning about Russia's interference in the U.S. election and political organizations last summer and failing to respond harshly.
