Attorney General Jeff Sessions is considering appointing a special counsel to investigate a range of Republican issues, The Washington Post reports. Among those concerns are Hillary Clinton’s use of a private email server and Russia’s purchase of Uranium One, a Canadian mining company with U.S. operations. President Donald Trump has previously tweeted about the issues and called on Sessions to investigate. Politicians and pundits have previously speculated that Republicans might attempt to appoint a second special counsel to investigate the Uranium One sale in an effort to discredit current special counsel Robert Mueller, who is investigating allegations of Russian meddling in the 2016 election. Mueller was FBI director at the time of the Uranium One sale and did not take action on the transaction, leading Republicans to accuse Mueller of Russian collusion. Appointing a second special counsel to investigate the first special counsel could potentially make Mueller’s investigation of the Trump campaign appear biased.
