President Joe Biden on Wednesday is expected to announce an additional $800 million in military aid for Ukraine, according to a White House official, bringing the total U.S. support for Ukraine to $1 billion in just the last week, writes USA TODAY.

Biden will announce the aid in an 11:45 a.m. ET speech, shortly after Ukraine President Volodymyr Zelenskyy is expected to urge for greater assistance during a virtual address to the U.S. Senate and House earlier in the morning.

“We’re moving urgently to further augment the support to the brave people of Ukraine as they defend their country. And I’ll have much more to say about this tomorrow - about exactly what we’re doing in Ukraine”, - Biden said.

The additional $800 million will mean more than $2 billion in U.S. aid has gone to Ukraine since Biden entered office. The money has paid for an assortment of military equipment including 600 Stinger anti-aircraft systems, 2,600 Javelin anti-armor systems, nearly 40 million rounds of small arms ammunition, 200 grenade launchers and ammunition, 200 shotguns and 200 machine guns, according to the White House.

In addition, Biden signed into law a government funding bill Tuesday that will provide $13.6 billion in humanitarian aid, economic support and defense assistance for Ukraine and the region.
