Lt. Col. Alexander Vindman, a national security aide, and Jennifer Williams, a top foreign policy aide to Vice President Mike Pence, testified Tuesday in the House impeachment inquiry, describing their firsthand knowledge of President Trump's dealings with Ukraine and his July 25 call with Ukrainian President Volodymyr Zelensky. Both Williams and Vindman were on the call. Williams said she found the call "unusual" and "inappropriate" and that no national security officials supported withholding Ukrainian aid. Vindman testified Trump was supposed to address Ukrainian corruption with Zelensky but didn't, undermining Trump's argument his request for investigations into his political opponents were about rooting out corruption.
