Vice President J.D. Vance's decision to jump into the fray and attack Ukraine President Volodymyr Zelensky during an Oval Office appearance on Friday was called out on MSNBC by a former White House official who claimed that was not his forum for speaking.

"Zelensky refused to abandon Kyiv, even after other leaders pleaded with him to leave.Trump hid in a bunker when protesters were outside the White House, then claimed he was inspecting the basement 🙄."

A remarkable shouting match broke out in the Oval Office on Friday between President Donald Trump and his Ukrainian counterpart Volodymyr Zelensky, an extraordinarily fractious display that only underscored the deeply uncertain future of American assistance to Kyiv.
