Washington, March 13 (Reuters) - U.S. Vice President JD Vance expressed skepticism on Thursday about President Donald Trump's potential endorsement of deploying nuclear weapons deeper into Europe. Vance's remarks came in response to Poland's president urging the U.S. to station such weapons on its soil to deter possible Russian aggression. "I haven't discussed this matter with the President, but I would be surprised if he favored extending nuclear weapons deeper into Europe," Vance mentioned during an interview on Fox News' "The Ingraham Angle."
