President Donald Trump is ordering a pause on shipments of US military aid to Ukraine after his heated Oval Office argument with Ukrainian President Volodymyr Zelensky last week, a White House official told CNN Monday.

The White House had no immediate comment on the scope and amount of aid affected or how long the pause would last.

The fallout from the heated exchange sparked criticism from Ukraine-backing lawmakers as well as praise from Republican supporters of the U.S. president.
