Sen. John McCain (R-Ariz.) said Wednesday he's sending a list of questions to the White House to get to the bottom of how Vice President Mike Pence was "lied to" by National Security Adviser Mike Flynn.

"First we need to ask questions and get answers and then decide" what to do, McCain said. "We will be doing that."


McCain has been perplexed this week about who in the administration is in charge of national security policy. Flynn resigned this week after misleading Pence about whether he discussed sanctions with the Russian ambassador. But rather than make new calls for probes into Trump and Russia, McCain wants to see if he can get answers from Trump officials first.

"I'm worried about a situation where the Vice President of the United States is lied to by the national security adviser," McCain said. "We need to ask questions and get answers."
