By Isabel Demetz and Jesus Calero (Reuters) -German Defence Minister Boris Pistorius is set to discuss the possibility of Germany paying for American Patriot air defence systems for Ukraine, as he heads to Washington to meet with U.

U.S. President Donald Trump’s special envoy to Ukraine, retired Lt. Gen. Keith Kellogg, arrived in Kyiv on Monday.

Sending U.S. Patriots marks a shift for Trump, who had previously refrained from approving new weapons shipments to Ukraine since he returned to the White House. It also comes as U.S. Senator Lindsey Graham announced record levels of U.S. arms would go to Ukraine, dealing a blow to Putin.
