Mueller hardens stance on Trump interview in Russia probe, Giuliani says

Special Counsel Robert Mueller wants President Donald Trump to commit to a follow-up interview to written answers to questions in his probe of any coordination between Trump campaign members and Russia in the 2016 US election, Rudy Giuliani, who is representing the president, said on Thursday.

Giuliani, who said talks between the two sides were continuing, saw Mueller's stance as a hardening in the position prosecutors are taking after offering to allow Trump to answer questions in writing.

"I thought we were close to having an agreement until they came back with, 'You have to agree now that you'll allow a follow-up,' and I don’t see how we can do it," Giuliani told Reuters.

Peter Carr, a spokesman for Mueller, declined to comment.
