The pressure is on House Republicans days ahead of a looming partial Homeland Security Department shutdown.

Senate GOP leaders have agreed to Democratic demands and announced legislation to fund the Homeland Security Department without contentious immigration provisions opposed by Democrats and President Barack Obama. Now all eyes are on the House GOP.

Early reviews from House conservatives are negative. They have a closed-door caucus meeting set for Wednesday morning.

Several insist they cannot accept the two-part strategy proposed by Senate Majority Leader Mitch McConnell. The first is a vote on legislation to fund the Homeland Security Department. The second: a separate vote to overturn Obama's executive actions sparing millions of immigrants in this country illegally from deportation.

Republican congressman Matt Salmon of Arizona says McConnell's plan is "tantamount to surrender."
