WASHINGTON/WEST PALM BEACH, Fla. (Reuters) - U.S. Attorney General William Barr pored over a special counsel report into Russian interference in the 2016 presidential election and whether the Trump campaign coordinated with Moscow, and was due to release key findings perhaps as early as Sunday. Barr, the top U.S. law enforcement official, aimed to transmit to Congress and the public a summary of Special Counsel Robert Mueller's report by the end of the weekend. There appeared to be initial good news for President Donald Trump and his inner circle, as Mueller did not bring any new indictments when handing over his report to Barr on Friday after a probe of almost two years.
