It’s not often that I feel ashamed to be an American. But I was ashamed this week when the Senate refused to support a supplemental spending bill that would provide about $61 billion in urgently needed aid for Ukraine (along with $14 billion for Israel and $20 billion for border security). All of the Senate Republicans, even those who have previously supported Ukraine funding, voted to filibuster the bill. Their stated position: They won’t provide a penny for Ukraine unless Democrats agree to a sweeping, draconian overhaul of the United States’ immigration laws.
