Donald Trump on Monday attributed the Democratic National Committee hack that led to the ouster of its chair to “one of our many, many ‘friends’” in Russia or China.

At a campaign event with running mate and Indiana Gov. Mike Pence in Roanoke, Virginia, Trump said although outgoing DNC chair Debbie Wasserman Schultz worked “very, very hard to rig the system” in favor the of presumptive nominee, Hillary Clinton “threw her under the bus” after emails between top DNC staffers were leaked online.

“Little did [Wasserman Schultz] know, Russia, China, one of our many, many ‘friends’” – Trump emphasized with air quotes – “came in and hacked the hell out of us. Can you imagine?”

Trump was discussing the cyber attack on the DNC, which has been widely attributed to Russian intelligence forces.

The public release of thousands of messages stolen from the DNC’s servers and published online Friday by Wikileaks has been a high-profile embarrassment for Wasserman Schultz and other top staffers, who discussed trying to get Broadway tickets to see “Hamilton” and weighed an attack on Sen. Bernie Sanders’ (I-VT) religious beliefs.
