The U.S. has spent $4 billion in pensions in Ukraine through its foreign aid during the war, according to a GOP congressman who sits on the House Foreign Affairs Committee.

Tennessee Republican Rep. Tim Burchett confronted Secretary of State Tony Blinken about taxpayer money going toward pensions in Ukraine during a House Foreign Affairs Committee hearing on Thursday.

In response, Blinken said there are processes in place to make sure the funds are going toward approved categories. He also said that most of the U.S. funding moves through a World Bank program.
