KEY POINTS
  • Vice President Mike Pence is delaying his Middle East trip as Senate Republicans push to pass their tax plan.
  • The GOP would need Pence's tiebreaking vote if two Republicans oppose the bill.

Vice President Mike Pence will push back a planned Middle East trip as the Senate tries to pass a bill that would overhaul the U.S. tax system, his office said Thursday.

If two of the 52 Senate Republicans oppose the tax plan in a vote expected by Tuesday, Pence would need to break a tie for the legislation to pass. He is now expected to leave the United States on Tuesday, rather than a planned Saturday departure date.
