WASHINGTON (Reuters) - Incoming U.S. Senate Democratic Leader Chuck Schumer on Friday said he is “very concerned” about Republican U.S. President-elect Donald Trump’s selection of Senator Jeff Sessions as attorney general and indicated there would be tough questioning in the chamber’s confirmation process. “Given some of his past statements and his staunch opposition to immigration reform, I am very concerned about what he would do with the Civil Rights Division at the Department of Justice and want to hear what he has to say,” Schumer said in a statement.
