Vice President Pence is delaying his planned trip to the Middle East until January as Congress prepares to vote on the GOP's tax bill.

Pence had planned to fly to Egypt Tuesday night and have a bilateral meeting with President Abdel Fattah al-Sisi on Wednesday before traveling to Israel and then Germany, according to reports.

The decision to postpone the trip comes after widespread outrage over President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

A spokeswoman for Pence's office said the decision was made to ensure that the GOP tax-cut bill is passed successfully.

“The largest tax cut in American history is a landmark accomplishment for President Trump and a relief to millions of hardworking Americans,” Pence’s press secretary Alyssa Farah said in a statement.

“The Vice President is committed to seeing the tax cut through to the finish line. The Vice President looks forward to traveling to Egypt and Israel in January," she said.

A White House official maintained that the tax vote is the sole reason for moving Pence's trip back, emphasizing that the "reaction in the Middle East to the President's Jerusalem decision did not play a factor in the decision to delay the trip."

Pence now is expected fly to the Middle East during the week of Jan. 14, The Washington Post reported, citing senior White House officials.

The vice president could be the tie-breaking vote in the Senate if Republicans are not able to garner enough support for the bill, although it appeared on Monday they had the votes after Sen.

World leaders like British Prime Minister Theresa May condemned the Trump administration's decision to recognize Jerusalem, calling it "unhelpful" to the delicate peace process between the Israelis and Palestinians.

Palestinian President Mahmoud Abbas announced earlier this month he would not meet with Pence in light of the decision, as did other regional leaders.
