THE HILL: Four members of Mueller’s team have donated to Democrats.

Four members of special counsel Robert Mueller’s team on the Russia probe have donated to Democratic presidential campaigns and organizations, according to Federal Election Commission filings.

Michael Dreeben, who serves as the Justice Department’s deputy solicitor general, is working on a part-time basis for Mueller, The Washington Post reported Friday.

Dreeben donated $1,000 dollars to Hillary Clinton’s Senate political action committee (PAC), Friends of Hillary, while she ran for public office in New York. Dreeben did so while he served as the deputy solicitor general at the Justice Department.

Jeannie Rhee, another member of Mueller’s team, donated $5,400 to Hillary Clinton’s presidential campaign PAC Hillary for America.

The political affiliations of Mueller’s team have been spotlighted by former House Speaker Newt Gingrich (R-Ga.) an ally of Trump.

After initially hailing Mueller’s appointment as special counsel, Gingrich questioned for former FBI director’s ability to be impartial on Monday because of “who he is hiring.” . . .

Two other members of Mueller’s team also have donated to Democrats.

Andrew Weissmann, who serves in a top post within the Justice Department’s fraud practice, is the most senior lawyer on the special counsel team, Bloomberg reported. He served as the FBI’s general counsel and the assistant director to Mueller when the special counsel was FBI director.

Before he worked at the FBI or Justice Department, Weissman worked at the law firm Jenner & Block LLP, during which he donated six times to political action committees for Obama in 2008 for a total of $4,700.

James Quarles, who served as an assistant special prosecutor on the Watergate Special Prosecution Force, has donated to over a dozen Democratic PACs since the late 1980s. He was also identified by the Washington Post as a member of Mueller’s team.

Starting in 1987, Quarles donated to Democratic candidate Michael Dukakis’s presidential PAC, Dukakis for President. Since then, he has also contributed in 1999 to Sen. Al Gore’s run for the presidency, then-Sen. John Kerry’s (D-Mass.) presidential bid in 2005, Obama’s presidential PAC in 2008 and 2012, and Clinton’s presidential pac Hillary for America in 2016.

Mueller’s hopelessly compromised. Nothing he does is going to be accepted as fair or impartial. He should step down.
