“He’s invited the help of foreign powers, he sided with [Russian President] Vladimir Putin Vladimir Vladimirovich PutinPutin nominated for Nobel Peace Prize Navalny released from hospital after suspected poisoning Ex-Trump national security adviser says US leaders 'making it easy for Putin' to meddle MORE on that stage in Helsinki, Finland, instead of our own intelligence community, so it’s no wonder that there is a lack of trust between military leaders, our intelligence community and the president of the United States,” O'Rourke said.

“This dynamic imperils the United States. It makes us less safe than we would otherwise be as his national security adviser and his cabinet push us into what perhaps will be another war with Iran," he added.

He further said that Trump “has made a mess of our foreign policy and has significantly diminished the national security of this country.”

His comments follow a New York Times report Saturday in which two administration officials said that that they did not think Trump was briefed in detail about efforts to ramp up digital attacks on a Russian power grid.

Trump denied the report in a pair of tweets on Saturday.

O'Rourke is among two dozen people vying for the Democratic Party's 2020 Presidential nomination.
