With the nation's attention Thursday morning focused on live coverage of fired FBI Director James Comey's testimony before the Senate Intelligence Committee, fresh calls for impeachment of President Donald Trump are reverberating after the director's "extraordinary" prepared statement was released Wednesday.

"We will not treat this as normal... Everyone in Congress must look in the mirror and decide how they will fulfill their oath to defend our Constitution—and which side of history they want to be on." —Anna Galland, MoveOn.org"

In the United States, no one is above the law," said Anna Galland, executive director of MoveOn.org. "The testimony that former FBI Director James Comey is expected to deliver today makes clear that Congress must begin impeachment proceedings immediately."

Comey's testimony, she continued, makes it clear that Trump attempted to use his powerful position "to interfere with an ongoing investigation of whether, how, and why a foreign power tried unlawfully to undermine our electoral process is exactly the kind of fundamental abuse of power that the founders believed is an impeachable offense—a 'High Crime or Misdemeanor' under our Constitution."

With support for for impeachment already showing strength and Trump's approval ratings dipping lower by the week, Galland said it will be up to Congress to hold the president to account. "We will not treat this as normal," she said. "And politicians in Washington must not continue to conduct business as usual. Everyone in Congress must look in the mirror and decide how they will fulfill their oath to defend our Constitution—and which side of history they want to be on."
