Senator Warren calls for law to protect Mueller

Senator Elizabeth Warren on Wednesday said that that there was an immediate need for a law to be passed by the Congress to protect special counsel Robert Mueller after two of United States President Donald Trump's former aides pleaded guilty in multiple criminal charges.

Warren, however, downplayed a question on impeachment charges against Trump, and reiterated that Mueller's protection must be the "top priority", The Hill reported.

Trump has been a vocal critic of Mueller's Russia probe and has repeatedly called it a "witch hunt" and "unnecessary." Mueller is currently investigating the possibility of Russian interference in the 2016 presidential poll and a possible collusion between Moscow and Trump's electoral campaign.

However, the US president remained silent on his former campaign chairman Paul Manafort, who was charged on eight counts of tax and bank fraud and personal lawyer Michael Cohen, who violated the financial law of Trump's campaign by arranging hush money payments for two women.

Earlier on Tuesday, a Virginia court found Manafort guilty on eight charges, including tax fraud. While the jury found Manafort guilty on five charges of filing false income tax returns, including for failing to report foreign bank accounts and on two counts of bank fraud, the judge declared a mistrial on the remaining 10 counts, including three counts of failing to report foreign bank accounts, five counts of bank fraud conspiracy and two counts of bank fraud.

On the other hand, Cohen pleaded guilty in Manhattan federal court in connection with eight criminal charges, including the arrangement of non-disclosure agreements of adult star Stormy Daniels and former Playboy model Karen McDougal over their alleged affairs with Trump.
