In a dramatic week in Washington, one of the most high-profile members of the Senate Intelligence Committee has become Independent Sen. Angus King. The senator from Maine made national headlines for his tough questioning of top intelligence officials and former FBI Director James Comey.

"The investigation isn't over," King during a veterans event in Bangor Friday.

King said the next steps in the Senate's Russia investigation include questioning Jared Kushner, the son-in-law and senior advisor of President Donald Trump; Trump's former campaign manager, Paul Manafort; his longtime confidante, Roger Stone; and attempting to speak with Michael Flynn, Trump's former national security adviser.

"We'll just have to see where the facts lead," said King, who stopped short of calling Comey's testimony a case for obstruction of justice charges against the president.

"That's up for [special prosecutor Robert] Mueller to determine," he said.

King said he found Comey to be credible and honest. He agreed with the former FBI director that the president saying "I hope you let this go" amounts to a directive to drop the Flynn investigation.

King said Congress is no closer to impeaching the president – and his committee is focused on the bigger picture: Russian meddling.

"The bigger issue that's getting lost in all of this is what the Russians did, and what they're going to do next time," said King.

He said his role as an independent is an important one, in a hyper-partisan time.

"Part of my job, I think, is to try and shepherd this in a bipartisan way so when we reach conclusions, the American people understand how we got there," he explained.
