The probe of Russian interference in the 2016 U.S. election and possible collusion by associates of President Donald Trump is not a "fishing expedition," the Justice Department official who launched it said.
In his first Sunday news-show appearance, U.S. Deputy Attorney General Rod Rosenstein declined comment on whether special counsel Robert Mueller, who's leading the investigation, is using a federal grand jury to help collect information. He said if Mueller finds evidence of a crime within the scope of the probe, he can investigate.
Rosenstein, 52, appointed Mueller, a former director of the Federal Bureau of Investigation, to lead the federal investigation in May after Attorney General Jeff Sessions recused himself.
