A group of leading House lawmakers have petitioned President Donald Trump to immediately move the U.S. Embassy in Israel to Jerusalem ahead of a deadline that could see the White House delaying the move for at least another six months, according to a letter sent to the president and obtained by the Washington Free Beacon.

Rep. Ron DeSantis (R., Fla.), chair of the House Subcommittee on National Security, spearheaded the letter, which urges Trump to finally make good on a heavily scrutinized campaign promise to relocate the U.S. Embassy in Israel from Tel Aviv to Jerusalem, the Jewish state’s capital city.

While Trump has promised to move the embassy—which Congress legally mandated in 1995—as one of his first moves in office, the White House sent shockwaves through the pro-Israel community earlier this year when it renewed a longstanding waiver that ignores the congressional mandate and requires the embassy to remain located in Tel Aviv.

Every president since the law was initiated has signed the waiver, claiming that moving the embassy would interfere with U.S. diplomatic efforts to restart Israeli-Palestinian peace talks. Many observers in Congress and elsewhere thought Trump would finally break that cycle.
