Vindman’s testimony turns the Ukraine defense into a credibility problem
Alexander Vindman, the White House national security official who listened in on Trump’s July 25 call with Ukraine’s president, was expected to tell congressional investigators that he was alarmed enough to raise concerns through official channels. That made him the first White House official with direct call access to testify in the impeachment inquiry, and it undercut the idea that the rough transcript was a harmless, exculpatory document. The day’s significance was not just what Vindman said, but what his appearance signaled: the pressure campaign was no longer a theory built from secondhand accounts.
