A bipartisan bloc of 17 House lawmakers is urging President Donald Trump to disinvite Turkish President Recep Tayyip Erdoğan from a planned White House visit on Wednesday.

In a letter led by House Foreign Affairs Chairman Eliot Engel (D-N.Y.), the 15 House Democrats and two Republicans said Turkey's invasion of northern Syria last month "has had disastrous consequences for U.S. national security, has led to deep divisions in the NATO alliance and caused a humanitarian crisis on the ground."

"Given this situation, we believe that now is a particularly inappropriate time for President Erdogan to visit the United States, and we urge you to rescind this invitation," the lawmakers wrote.

Lawmakers also cited Turkey's purchase of the Russian-made S-400 missile system and other moves that have drawn the NATO ally closer to Moscow as well as Erdoğan's undermining of domestic democratic institutions.

The Turkish president is slated to visit the White House and hold a joint press conference with Trump on the same day as the first public hearing of the House impeachment inquiry into the president's dealings with Ukraine.

The White House had no immediate comment on the congressional letter.

Erdoğan's visit comes at a particularly fraught time in U.S.-Turkey relations.

Last month, the House overwhelmingly condemned the U.S. pullout from northern Syria and subsequent Turkish military campaign against Kurdish forces the U.S. partnered with in the fight against ISIS.

House lawmakers also passed sweeping sanctions legislation targeting arms sales to Turkey, financial institutions and top Turkish military officials.

The U.S. has also booted Turkey from its F-35 fighter program after it took delivery of the S-400 missile system, rebuffing warnings from lawmakers and administration officials as well as a counteroffer to purchase the U.S.-made Patriot missile system.

In an interview on Sunday, White House national security adviser Robert O'Brien said Trump plans to confront Erdoğan during his White House visit over the purchase of the S-400 and warned Turkey will "feel the impact" of sanctions if it keeps the platform.
