Former New York Mayor Rudy Giuliani, who is now on President Trump’s legal team, told CBS News correspondent Paula Reid Monday that special counsel Robert Mueller’s office has rejected proposals to allow Mr. Trump to answer questions from investigators in writing.

The president’s legal team has signaled that this would be their preferred format for a possible interview, since it helps protect Mr. Trump from the possibility of lying or misleading investigators, which is a criminal offense.

Giuliani told CBS News it will take up to three weeks for him to get fully up to speed on the facts of the investigation and be prepared to engage in formal negotiations with the special counsel about the terms of a possible interview with Mr. Trump.  

Giuliani told Reid that he and the president’s legal team continue to be in communication with the special counsel, but that he wants to have a better sense of the facts before engaging in formal negotiations about a possible interview.
