(This January 16 story corrects sixth paragraph to say Republicans hold 53 rather than 52 seats in the 100-seat Senate.) By Sarah N. Lynch WASHINGTON (Reuters) - Senate Democratic leader Charles Schumer said on Wednesday he will oppose President Donald Trump's attorney general nominee, William Barr, saying he is not convinced that Barr will protect Special Counsel Robert Mueller's Russia probe or provide Congress with a full report on Mueller's findings. "We do not have the kind of strong and clear commitments to the report being issued and there being no interference in the investigation that are needed, particularly now, with President Trump treating the Justice Department as he has," Schumer told reporters following a private meeting with Barr.
