In what would be a reversal, the Biden administration is poised to approve sending M1 Abrams tanks to Ukraine, U.S. officials said Tuesday, as international reluctance toward sending tanks to the battlefront against the Russians begins to erode. The decision could be announced as soon as Wednesday though it could take months or years for the tanks to be delivered. (Christian Murdock/The Gazette via AP, File)
