Former Director of National Intelligence James Clapper said that President Trump is attacking government institutions laid out by the founding fathers.

"The developments of the past week are very bothersome [and] disturbing to me," Clapper said on CNN.

"Our institutions are under assault... internally," Clapper, who served the intelligence community in every administration since President George H. Bush, said.

He said the Founding Fathers laid out a system of checks and balances, coequal branches of government and levers of oversight.

"I feel as though that's under assault and is eroding," he said.

Clapper nodded when host Jake Tapper asked if he meant President Trump is to blame.

He also discussed Russian interference in the 2016 election and said he hopes legislators will use their "conscience" in the aftermath of Comey's dismissal.

"I hope they'll speak up," he said.
