President-elect Donald Trump said he “vehemently” disagrees with the Biden administration’s decision to allow Ukraine to use U.S.-provided weapons to hit military targets deep within Russian territory.

The current administration lifted long-held restrictions on Ukraine’s usage of U.S.-provided weapons last month in response to North Korea’s deployment of thousands of troops to Russia to use in the war. Ukrainian leaders had been asking for loosened rules for over a year, which President Joe Biden‘s administration had repeatedly declined.
