NBC News: 'Extremely disturbing': Top Democrats alarmed over Vindman's testimony on Trump-Ukraine call
Wasserman Schultz, D-Fla., a member of the House Oversight Committee who was present for the deposition, told NBC News that Vindman was a “very credible” witness and said his testimony "corroborated the testimony of other witnesses" that "really drew a direct line to the President, and those around him and their interest in withholding foreign aid through Ukraine that was vital, as well as insisting on investigations into Biden."
