Graham is usually a vocal supporter of U.S. President Donald Trump, but he has repeatedly publicly condemned Trump's decision to withdraw U.S. troops from northeastern Syria, which was quickly followed by a Turkish invasion to drive out Kurdish-led forces who have long been Washington's allies.
"Just spoke with Speaker Pelosi regarding congressional action on Turkey's incursion of Syria," Graham tweeted. "Speaker supports bipartisan sanctions against Turkey's outrages in Syria. She also believes we should show support for Kurdish allies and is concerned about the reemergence of ISIS."
