Fox News host Tucker Carlson tore into Ohio GOP Rep. Mike Turner on Wednesday night over claims that more American troops need to be sent overseas.

During a segment on Tucker Carlson Tonight, the host noted that Turner and 14 other Republicans wrote a letter to Joe Biden calling on him “to immediately provide support to the Ukrainians” after satellite images showed a buildup of Russian military forces along Ukraine’s northern border.

Carlson, however, did not support the move and argued that he did not understand why “average Americans” needed to go protect the “territorial integrity of Ukraine” and not the U.S.-Mexico border.
