The Republican chairmen of the House and Senate Armed Services Committees criticized on Saturday President Donald Trump’s move to withdraw 5,000 U.S. troops from Germany, amid a feud with German Chancellor Friedrich Merz.

Senate Armed Services Committee Chairman Roger Wicker (R-MS) and House Armed Services Committee Chairman Mike Rogers (R-AL) released a joint statement saying they were “very concerned” over the Trump administration’s Friday announcement that 5,000 troops would be withdrawn from Germany. In the statement, the duo praised Merz’s role in boosting Germany’s defense spending and providing limited logistical support for U.S. forces in Operation Epic Fury.
