Mueller convenes a criminal grand jury for Russia investigation
Special counsel Robert Mueller Thursday convened a criminal grand jury to question witnesses on oath for his probe of Russian interference in the US 2016 election. He is expected to call Donald Trump JR on his meeting with a Russian lawyer who promised damaging information about Hillary Clinton, the president’s son-in-law and senior adviser Jared Kushner and former campaign manager Paul Manafort. President Trump has denounced the probe as a witch hunt and accused Mueller and his aides of partisan bias.
