As the Russian invasion nears its fourth month, President Joe Biden signed legislation Saturday to provide additional U.S. aid of $40 billion for Ukraine.

Congress passed the legislation with bipartisan support. This strengthens U.S. support for Ukraine during uncertain times. While Ukraine has successfully defended Kyiv and Russia has refocused their offensive against the country’s eastern side, American officials are concerned about the possibility of a long-term conflict.

This funding will support Ukraine until September and is much more than an emergency fund that had provided $13.6 billion.

New legislation provides $20 billion of military aid, which will ensure a constant stream of weapons technology that has been used to stop Russia’s advancements. A total of $8 billion is available in general economic aid, with $5 billion being allocated to deal with global food shortages caused by the collapse and $1 billion going to refugees.

Biden signed this measure in unusual circumstances. According to White House officials, Biden signed the measure while on an unusual trip to Asia.

These logistics show a feeling of urgency about continuing U.S. assistance for Ukraine and also reflect the multiple international challenges faced by Biden. While he is trying to redirect American foreign policies to face China, he will continue to focus resources on the most significant conflict in Europe since World War II.

Biden also signed a separate measure that would increase availability of baby formula during a difficult time in America’s supply. The legislation will allow government benefits from the Special Supplemental Nutrition Program for Women, Infants, and Children — better known as WIC — to be used to buy more types of infant formula.
