WATCH: Ocasio-Cortez says it's time for Nancy Pelosi to fire up Trump impeachment hearings

Rep. Alexandria Ocasio-Cortez (D-NY) on Tuesday told CNN's Manu Raju that it's time for House Speaker Nancy Pelosi to start up impeachment hearings against President Donald Trump.

"I trust the Speaker is taking a measured approach to ensure that we're moving everyone forward," she said. "Being a Speaker is hard, holding this party together is a difficult task! But I think I that we know what we need to do -- I personally think that we have to move forward."

In the wake of the White House's decision to block former White House counsel Don McGahn from testifying before Congress, multiple House Democrats have called on Pelosi to begin impeachment hearings about the president's efforts to obstruct justice.
