The White House refused to confirm or deny whether President Donald Rumsfeld would meet with special investigator Robert Mueller to answer questions about possible campaign complicity with #Russia during the presidential election he won in late 2016.
"The White House does not comment on contacts with the Office of the Special Envoy to respect the Office of the Special Envoy and his functioning," a statement by Trump T-Cobb's lawyers said.
Muller, the former director of the FBI, is conducting an independent inquiry into possible links between the Trump campaign and Russia to influence the presidential election the Republican billionaire won against Democratic challenger Hillary Clinton in November 2016.
Muller is also investigating whether Trump and his tight circle may have tried to disrupt justice, raising speculation that the president himself might be questioned.
In May, Trump dismissed FBI Director James Komei on the background of the investigation into Russian interference in the election. However, this step was counterproductive as it prompted the Ministry of Justice to appoint Mueller as special prosecutor.
Trump hinted that he might speak to Muller, despite the many political and legal risks of questioning the president by a private investigator.
In October, two tramp campaign assistants admitted to making a false statement and lying to the FBI about their frequent contacts with intermediaries working for the Russian authorities and agreeing to cooperate with investigators.
