President Donald Trump complained Monday that Robert Mueller has thus far ignored Trump 2016 campaign staff who the president said want to be interviewed for the special counsel's Russia investigation, renewing his attacks on Mueller's probe into allegations of collusion between Trump's campaign and the Russian government as biased.

"[W]ill he be putting in statements from hundreds of people closely involved with my campaign who never met, saw or spoke to a Russian during this period?" the president wrote, referring to Mueller's expected final report. "So many campaign workers, people inside from the beginning, ask me why they have not been called (they want to be)."


Mueller is investigating whether Trump's presidential campaign colluded with the Russian government's efforts to interfere in the 2016 presidential election, but has also expanded it to possible obstruction of justice by the president. The president earlier this month submitted written responses to questions related to Russian cyberattacks during the 2016 election.

Trump has repeatedly alleged that Mueller has conflicts of interests in his Russia investigation, including his ties to former FBI Director James Comey, who Trump fired, and a dispute over the special counsel's former membership at Trump National Golf Club in Loudoun County, Virginia.

"When Mueller does his final report, will he be covering all of his conflicts of interest in a preamble, will he be recommending action on all of the crimes of many kinds from those 'on the other side'(whatever happened to Podesta?)" Trump also wrote on Twitter.

It is unclear whether the president was referring to Hillary Clinton's former campaign chairman John Podesta, or his brother and lobbyist Tony Podesta, who currently is under federal investigation as a result of a referral from Mueller's office.

Trump has long labeled Mueller's investigation a "witch hunt" and has complained that Mueller's nomination as special counsel was not approved by Congress. Special counselors and other similar appointments are not required to be confirmed by Congress.

It is unclear when Mueller's investigation will come to a close.

"There was NO Collusion & Mueller knows it!" Trump wrote in his tweet.
