Sen. John McCain called for a select committee Wednesday to investigate Russia's involvement in the presidential election because "what the American people have found out so far, that no longer does the Congress have credibility to handle this alone."
"I don't say that lightly," the Arizona Republican told Greta Van Susteren on MSNBC.
McCain noted the top members of the House Intelligence Committee, Republican Devin Nunes and Democrat Adam Schiff, both of California, made widely conflicting statements on data that had been obtained by intelligence agencies through a procedure called "incidental collection."
Nunes said information about communications between Trump campaign staff, possibly President Donald Trump himself, were "swept up" in the process — and Schiff said Nunes' disclosure to the president before committee members jeopardized their investigation.
"This just shows a tremendous chasm between the two senior members of the House Intelligence Committee," McCain told Van Susteren. "What we need is a select committee.
"We know that the Russians interfered with our election – they did not achieve in effecting the outcome – but we know that for sure.
"We know that there are cyberattacks going on all the time. There are leaks going on all the time.
"What we need to address is this whole issue of what the Russians did, how they did it, its impact, and what we do about it."
