They appeared to have significant Republican support. Senator Mitch McConnell of Kentucky, the majority leader, reiterated his concern on Monday that the withdrawal would create “a catastrophic outcome for the United States’ strategic interests.”
Speaker Nancy Pelosi of California and Senator Lindsey Graham, Republican of South Carolina, spoke by phone on Monday and agreed that a bipartisan, bicameral joint resolution to overturn the president’s decision was their “first order of business,” Ms. Pelosi said.
Mr. Trump himself had cleared the way for the Turkish invasion and attacks on Kurdish forces allied with the United States by ordering the withdrawal of some American forces in northern Syria a week ago.
Some analysts of the United States-Turkey relationship cast Mr. Trump’s move as a half-measure, perhaps intended to forestall more aggressive action by an angry Congress.
“Trump’s ‘sanctions package’ against Turkey regarding the latter’s Syria offensive isn’t surprising,” Soner Cagaptay, a fellow at the Washington Institute for Near East Policy, wrote on Twitter. Mr. Trump, he said, “wasn’t really going to sanction Turkey for a move for which he had green lighted Erdogan in the first place.”
Mr. Trump said the steel tariffs on Turkey would rise to 50 percent from 25 percent. The United States had previously imposed a 50 percent steel tariff on Turkey last year after the Turkish government refused to release an American pastor who was being held on espionage charges. His decision to impose the tariffs in 2018 spooked markets and sent Turkey’s currency, the lira, tumbling.
Turkey was America’s sixth-largest foreign supplier of steel before the United States doubled the tariffs last year. Steel imports from Turkey fell sharply, dropping by 76 percent, after the tariff increase. Mr. Trump moved in May to pull the tariffs back to 25 percent, which is in line with duties that he imposed globally for national security reasons.
Mr. Trump’s statement made no mention of the potentially awkward fact that Mr. Erdogan is scheduled to visit Mr. Trump at the White House on Nov. 13, as Mr. Trump announced on Twitter last week. Nor did it mention possible sanctions that senators from both parties have insisted for months are required by law to punish Ankara’s purchase of an advanced Russian antimissile system.
