Story highlights "The vice president stands by his comments in March," an aide said

The question of what Pence knew and when first arose months earlier

Washington (CNN) Vice President Mike Pence is standing by a March statement that he first learned of now-fired national security adviser Michael Flynn's ties to Turkey from media reports, despite renewed scrutiny and revelations President Donald Trump's transition team was made aware far earlier.

"The vice president stands by his comments in March upon first hearing the news regarding General Flynn's ties to Turkey and fully supports the President's decision to ask for General Flynn's resignation," said an aide to Pence, who declined to be named.

But questions about what Pence knew and when are swirling thanks to new media reports about what Flynn revealed to Trump's transition team, which Pence oversaw.

Flynn informed the Trump transition team more than two weeks before the inauguration that he was under federal investigation for his work as a lobbyist advocating for Turkish government interests, The New York Times reported Wednesday . But Pence didn't know, according to a senior administration official close to Pence.

Despite reportedly informing the transition's chief lawyer Donald McGahn, now White House counsel, of the investigation's existence, Flynn still walked into the West Wing on January 20 as the President's top adviser on national security issues.
