The House Judiciary Committee launched a broad investigation into President Trump's inner circle Monday, targeting figures who have worked in his administration and for the Trump Organization businesses.

Justice Department special counsel Robert Mueller's office wants to interview the man who has been described as the link between WikiLeaks and Donald Trump's inner circle.

Former radio host Randy Credico — who denies serving as that link but says he has served as a go-between at other times to WikiLeaks — told NPR that a prosecutor working for Mueller had asked him for a voluntary meeting.

Credico said he declined. The special counsel's office declined to comment.
