MSNBC's "Hardball" discusses the newly released impeachment inquiry testimony from former U.S. ambassador to Ukraine Gordon Sondland. According to Sondland's updated testimony, he "now recalls" telling a top aide to President Zelensky "that resumption of the U.S. aid would likely not occur until Ukraine provided the public anti-corruption statement,” a statement committing Ukraine to investigate Trump's political opponents. With his revelation, Sondland has become the fourth witness to affirm a quid pro quo: military aid in exchange for political dirt.
