Rudy Giuliani, the president’s personal attorney, isn’t making many public appearances these days. Perhaps he’s been silenced by the White House, or maybe he’s spending more time working on his own defense. As Politico reports, his troubles are mounting.

The scrutiny isn’t just coming from the previously known probes by FBI agents and the U.S. attorney’s office based out of Manhattan, according to two people familiar with the investigation. The criminal division of the Justice Department in Washington has taken an interest in the former New York mayor, too, meaning an expansion of resources that indicates the politically sensitive probe into the president’s personal attorney is both broader and moving at a faster pace than previously understood.

Politico writes that Giuliani wasn’t at the White House earlier this week for a meeting with Trump and his legal team on impeachment strategy. Also, Giuliani hasn’t been on television in two weeks.

Should Giuliani be concerned? NPR writes:

There is ample reason for Giuliani to be worried, legal experts tell NPR. They point to a range of activities in which Giuliani has engaged over the years that may be of interest to investigators.

The most recent of these, of course, is tied to Ukraine and Giuliani’s connections to two recently indicted associates, Lev Parnas and Igor Fruman.

The pair face conspiracy, false statement and other charges linked to alleged campaign finance violations.
