The Trump administration is weighing whether to block former FBI Director James Comey's testimony to lawmakers next week.

White House press secretary Sean Spicer was asked Friday whether President Trump might invoke executive privilege to prevent Comey, who was fired by Trump last month, from speaking to the Senate intelligence panel as part of its investigation into Russian meddling in the 2016 election and possible collusion between the Russians and the Trump campaign.

While he said the issue has "got to be reviewed," Spicer didn't say whether a decision had been made.

"My understanding is the date for that hearing was just set. I haven't spoken to counsel yet. I don't know how they're going to respond," he said.

A White House official later confirmed to Bloomberg that the Trump administration is reviewing the matter. If executive privilege is invoked, it could be challenged in court.

Comey is expected to tell lawmakers about his private conversations with Trump. According to a Comey memo, reported by the New York Times last month, Trump had asked Comey to lay off his agency's investigation into former national security adviser Mike Flynn. Flynn was fired after it was revealed that he mislead the Trump administration about his communications with a Russian envoy.
