Defense Secretary Lloyd Austin briefed President Joe Biden on Saturday about U.S. options for responding if Russia invades Ukraine, as well as options for U.S. military movements in advance of an invasion, according to a defense official and a senior administration official.
Among the options presented for the U.S. military in advance of an invasion were bomber flights over the region, ship visits into the Black Sea and the moving of troops and some equipment from other parts of Europe into Poland, Romania and other countries neighboring Ukraine.
