WASHINGTON (AP) — The Senate is returning to Washington on Tuesday to vote on $95 billion in war aid to Ukraine, Israel and Taiwan, taking the final steps in Congress to send the legislation to President Joe Biden’s desk after months of delays and contentious internal debate over how involved the United States should be abroad.

The $61 billion for Ukraine comes as the war-torn country desperately needs new firepower and as Russian President Vladimir Putin has stepped up his attacks. Soldiers have struggled to hold the front lines as Russia has seized the momentum on the battlefield and forced Ukraine to cede significant territory.

Biden told Ukrainian President Volodymyr Zelenskyy on Monday the U.S. will soon send badly needed air defense weaponry. The House approved the package Saturday in a series of four votes, sending it back to the Senate for final approval.
