German Defense Minister Christine Lambrecht has resigned amid mounting criticism from some NATO members over the pace of Germany’s aid to Ukraine. On Monday, German Chancellor Olaf Scholz toured a German weapons factory, promising to appoint a new defense minister soon.

Chancellor Olaf Scholz: “What is important is that when we set about the future of our country, we know that Germany needs a strong military and an efficient defense industry.”

Last year, the German chancellor pledged to spend over $100 billion to expand Germany’s military.
