House and Senate Republicans are having their first big family feud since taking control of Congress, as they hit a rock-hard budget impasse that threatens to trigger a partial shutdown of the Department of Homeland Security.

After a solid 16 months without a government shutdown of any kind, Congress is careening toward an end-of-the-month funding deadline for DHS without a new budget.

The House already passed a bill that includes provisions overturning President Obama's controversial immigration executive actions. But despite repeated attempts last week, the Senate was unable to pass that bill -- as Democrats blocked it, over and over again. Democrats want the immigration provisions stripped.

Yet House Republican leaders are refusing to take another crack at the bill. A senior House GOP leadership aide told Fox News there is no backup plan -- they are insisting the House-passed bill is the only proposal.
