Trump creates uncertainty about border bills

President Donald Trump is fueling uncertainty about an already shaky House GOP immigration overhaul, questioning "the purpose of the House doing good immigration bills when you need nine votes by Democrats in the Senate."

Trump tweeted Thursday that "the Dems are only looking to Obstruct (which they feel is good for them in the Mid-Terms)." He adds: "Republicans must get rid of the stupid Filibuster Rule-it is killing you!"

Trump's tweet comes as the House plans to vote on two immigration bills. House Republican leaders are still trying to build support for one negotiated among conservative and moderate factions of the GOP.

The president has said previously that he wants to change the Senate's rules to eliminate the filibuster, and allow passage of all bills on a simple-majority vote.
