President Joe Biden has signed a bipartisan bill providing billions of dollars in aid to Ukraine and a separate bill banning the popular video-sharing app TikTok in the United States. The Ukraine aid package was approved after months of negotiations between the Biden administration and Republicans in Congress, while the TikTok ban is intended to address concerns about the platform’s ties to the Chinese government. The legislation signing represents a significant victory for Biden, who has made strengthening US alliances and supporting Ukraine’s defense against Russia key foreign policy goals.
