U.S. Senate Republican leader Mitch McConnell has rejected President Joe Biden's budget plan, saying it is inadequate on defense spending at a time of heightened international tensions over Ukraine. The proposed $5.8 trillion budget for the 2023 fiscal year calls for record peacetime military spending and further aid for Ukraine. It includes a national defense budget of $813 billion, a 4 percent increase from the spending package signed into law earlier this month for this fiscal year.
