Nebraska Senator Pete Ricketts finds himself in a challenging position, emphasizing the urgency of U.S. border security over a recent Senate vote on military aid to Ukraine. Ricketts believes that safeguarding the southern border is the most critical national security issue at the moment. In a bipartisan Senate vote, a $95 billion emergency defense spending bill, including $60 billion for Ukraine, was passed. However, Ricketts, along with many Republicans, opposed the bill, insisting on addressing border security concerns first.
