Ukraine’s President Volodymyr Zelenskyy made a dramatic visit to Washington Wednesday — his first known trip outside Ukraine since the Russian invasion began in February.

He met with President Joe Biden at the White House and later addressed Congress as lawmakers are set to vote on $45 billion more in emergency aid as part of a larger spending package. Biden on Wednesday also announced the U.S. will send Ukraine a Patriot anti-missile battery to defend against devastating Russian attacks.

In a virtual address to U.S. lawmakers back in March, Zelenskyy emotionally pleaded for more aggressive measures to help fight the war. Invoking key American tragedies, including Pearl Harbor and the Sept. 11 attacks, Zelenskyy told members at the time, “Just remember it … Our country experiences the same every day right now.”
