Vietor's comment came after Trump railed against Clinton and called on the FBI and Justice Department to investigate the former secretary of State for a number of allegations.

Among the allegations listed by Trump were that she "stole" the Democratic primary and improperly used a private email server during her tenure at the State Department.

He also said that law enforcement should probe an Obama-era deal that put Russia in control of 20 percent of the U.S. uranium stockpile. That deal was approved by the State Department under Clinton, though she has claimed she was not involved in the decision.

Clinton's use of a private email server while serving as secretary of State was already the subject of an FBI probe. No charges were brought against her as a result of that investigation, though Trump and his allies have raised concerns about the probe.

Trump has repeatedly accused Clinton of wrongdoing and has urged the Justice Department to investigate her instead of carrying on its current probes into Russia's role in the 2016 election and possible collusion between his campaign and Moscow.

He has called the special counsel investigation into Russian election meddling a political "witch hunt" propagated by Democrats as an excuse for Clinton's loss in the 2016 election.
