Turkish President Recep Tayyip Erdogan will be feted Wednesday at the White House despite his attacks on a longtime U.S. ally, his purchase of military equipment from Russia and calls from lawmakers in both parties to punish him.

President Donald Trump and top aides have ignored bipartisan calls to cancel Erdogan’s visit, which is expected to include a joint press conference on the same day public hearings in the House impeachment inquiry begin.

Though largely united against the Democratic impeachment effort, Trump and many congressional Republicans are at odds over what to do after Turkey’s invasion of northern Syria to attack Kurdish forces.

Several Republicans were among 17 House members who signed a letter from Foreign Affairs Chairman Eliot L. Engel of New York, calling on Trump to rescind Erdogan’s invitation.

Those 17 lawmakers said the Turkish leader’s “calamitous actions” followed a “long list of disconcerting steps under his leadership.” House Republican Conference Chairwoman Liz Cheney of Wyoming also wrote to Secretary of State Mike Pompeo on Monday, urging him to bar from the United States any members of Erdogan’s security detail who were caught on camera last year physically engaging protestors near the Turkish ambassador’s residence.
