Marie Yovanovitch, the former U.S. ambassador to Ukraine, testified Friday before the House Intelligence Committee, the second day of impeachment hearings against President Trump.

How is it that foreign corrupt interests could manipulate our government?"

She also discussed what led to her dismissal.
