White House press secretary Sarah Sanders has been interviewed as part of special counsel Robert Mueller�s Russia investigation.

Sanders says in a statement released Friday that she was �happy to voluntarily� sit for the interview. It was unclear when Sanders was interviewed but she says her boss, President Donald Trump, urged her to �fully cooperate.�

CNN was first to report on Sanders� interview.

Mueller is believed to be close to wrapping up his investigation into possible collusion between Trump�s presidential campaign and the Russian government. Trump has denied collusion and has denounced the investigation as a political �witch hunt.� Sanders has also used the �witch hunt� language to describe Mueller�s inquiry.
