WASHINGTON — President Donald Trump has not yet decided whether to recognize Jerusalem as Israel’s capital or whether to proceed immediately in moving the U.S. Embassy from Tel Aviv to the holy city. That’s according to his son-in-law and senior adviser, Jared Kushner.

Kushner said Sunday that the president continues to weigh his options ahead of an announcement on the matter that is expected this week.

“The president is going to make his decision,” Kushner said in a rare public appearance at an event hosted by the Brookings Institution, a Washington think tank. “He is still looking at a lot of different facts.”

Kushner’s comments were his first public remarks on his efforts to restart peace talks between Israel and the Palestinians. And, they came as he faces increasing scrutiny over actions taken during the transition period following former national security adviser Michael Flynn’s guilty plea on charges of lying to the FBI.

Shortly before Kushner spoke, Palestinian President Mahmoud Abbas warned that American recognition of Jerusalem as Israel’s capital would jeopardize the White House’s Mideast peace efforts.

“Any American step related to the recognition of Jerusalem as capital of Israel, or moving the U.S. Embassy to Jerusalem, represents a threat to the future of the peace process and is unacceptable for the Palestinians, Arabs and internationally,” Abbas told a group of Arab lawmakers from Israel, according to the official Wafa news agency.

U.S. officials said last week that Trump is poised to recognize Jerusalem as Israel’s capital in a move that would upend decades of U.S. policy but also to put off once again moving the embassy from Tel Aviv. The officials said Trump is expected to make his decision known in a speech on Wednesday.

The highly charged declaration risks inflaming tensions across the Middle East.
