Meet special counsel Robert Mueller's prosecution team

Mueller has added two prosecutors to his legal team since the probe began.

In addition to a squad of agents from the Federal Bureau of Investigation (FBI) and the Internal Revenue Service (IRS), Mueller now has 18 attorneys on staff, a spokesperson for Special Counsel Robert Mueller confirmed to ABC News.

Mueller’s team has come under fire in the past year for perceived biases against the President. Conservatives have pointed to team members’ donations to Democratic causes as a major red flag, as well as a 2016 cache of text messages disparaging then-candidate Trump recovered from former team members FBI Agent Peter Strzok and FBI lawyer Lisa Page. Justice Department guidelines do not allow consideration of party affiliation to affect personnel decisions. Special counsel Mueller himself has been a registered Republican in the past and was first appointed FBI Director by President George W. Bush.

These 18 attorneys are confirmed members of Mueller’s team:

Zainab Ahmad is an attorney on loan from the Eastern District of New York, where she served as a deputy chief of the National Security and Cybercrime section before being loaned to Mueller’s team. Ahmad made a name for herself prosecuting terrorist suspects in New York, including Lawal Babafemi and Najibullah Zazi, the would-be al-Qaeda subway bomber. The authorities initially tracked down Zazi by following information from Ahmad’s prosecution of Abid Naseer, a Pakistani man who had been plotting an attack on a shopping center in the United Kingdom. According to a 2017 New Yorker profile, Ahmad has prosecuted and won thirteen terrorism cases since 2009.

Greg Andres, a former partner at the New York law firm Davis, Polk & Wardell, served as a former deputy assistant attorney general in the Justice Department’s Criminal Division Fraud and Appellate Sections and before that as an assistant U.S. attorney for the Eastern District of New York. Andres is a Justice Department veteran specializing in financial crimes. He gained a wealth of experience in public and private sector anti-corruption investigations, including insider trading, money laundering and tax fraud. Andres has given $3,800 to Democratic candidates and causes, including $1,100 to David Hoffman during his Senate race in 2009 and $2,700 to Sen. Kirsten Gillibrand, D-N.Y., in 2017.

Uzo Asonye, currently an assistant U.S. attorney in the Eastern District of Virginia, joined the special counsel’s office to serve as its local counsel in the trial of Trump’s former campaign chairman Paul Manafort, located in Eastern District of Virginia. According to his LinkedIn page, Asonye also worked in the White Collar Defense and Corporate Investigations Group of the law firm O’Melveny and Myers. Federal Elections Commission (FEC) records show that Asonye donated $800 to the Clinton campaign in 2008. Asonye has previously prosecuted embezzlement and bribery cases, amongst others, including the successful 2016 prosecution of a former U.S. contractor based in the Embassy in Baghdad charged with accepting cash payments to gain electrical construction contracts in Iraq.

He most recently served in the criminal division’s Computer Crime and Intellectual Property Section. Most famously, Dickey helped prosecute the Romanian hacker “Guccifer” in 2016. The Romanian hacker is often confused with “Guccifer 2.0,” a different hacker who allegedly hacked the Democratic National Committee in 2016. Guccifer pleaded guilty to hacking into the emails and social media accounts of numerous high-profile victims, including former Secretary of State Colin Powell and family members of former President George W. Bush.

He is reputed to have an encyclopedic knowledge of criminal law and has argued over 100 cases before the Supreme Court. Harold Koh, the former Obama administration legal adviser to the State Department, worked with Dreeben and compared him to NBA superstar Shaquille O’Neal. Koh described Dreeben to ABC News as “the best in the business … [he’s] the best appellate criminal law specialist in the country.” On May 4, Dreeben sparred in court with federal Judge T.S. Ellis during a hearing over dismissal of the 32-count indictment against Manafort.

Kyle Freeny is an attorney on detail from the DOJ’s Criminal Division’s Money Laundering and Asset Recovery Section. In 2016, she was part of a Justice Department team seeking to recover over $1 billion from an alleged corrupt Malaysian sovereign wealth fund.

Goldstein investigated and prosecuted the CityTime case, which the Department of Justice then referred to as “the largest municipal fraud and kickback scheme in history.” Goldstein received further praise from Bharara upon his June appointment to the Mueller probe, when Bharara tweeted, “Best of best in every way. Fair, tough, smart.” Goldstein donated more than $750 to Obama’s 2012 campaign and more than $2,800 to Obama’s 2008 campaign.

Adam Jed is an appellate attorney on detail from the DOJ’s Civil Division. A former clerk for U.S. Supreme Court Justice John Paul Stevens, Jed received the Attorney General’s Award for Exceptional Service in 2014, following his work on the successful implementation of the Supreme Court’s decision that struck down the Defense of Marriage Act, a law barring the federal government from recognizing same-sex marriages legalized by the states.

Scott Meisler joined the special counsel in June 2017, according to Mueller spokesman Peter Carr. Meisler joined the special counsel in June 2017.

George Allen in 2005.

Jeannie Rhee is a former partner at the law firm WilmerHale, who has served in the Office of Legal Counsel and as an assistant U.S. attorney for the District of Columbia. “She’s a top financial and fraud prosecutor… having spent years at the U.S. Attorney’s Office in Washington,” ABC News contributor and former director of the National Counterterrorism Center Matt Olsen said. Mueller’s appointment of Rhee drew the ire of conservative commentators, owing in part to large sums she had donated to Democratic campaigns -- $5,400 to Clinton in 2015 and 2016, and $4,800 to the Obama campaign in 2008 and 2011, as well as $4,800 in further donations to the Obama Victory Fund. Additionally, Rhee donated more than $3,000 to other Democratic causes since 2004. Conservatives also took aim at Rhee’s defense of the Clinton Foundation in a 2015 case after she left the Obama administration in 2011 and entered private practice at WilmerHale.

Brian Richardson, a former Supreme Court clerk under Justice Stephen Breyer, joined the special counsel in July 2017. He also served as a clerk for the U.S. Court of Appeals for the 2nd Circuit from 2013 to 2014.

Before that, Weissmann served in the Eastern District of New York’s U.S. Attorney’s Office, where, according to the Justice Department, he was “instrumental in bringing to justice high-ranking members” of New York’s toughest crime families. While a partner at the law firm Jenner & Block in 2008, Weissmann donated a total of $4,700 to the Obama campaign and Victory Fund.

Koh calls Zelinsky “an incredible team leader.”

Two FBI veterans have left the team since its inception.

Peter Strzok, who had been tapped by Mueller to help lead the probe, left the team last summer, sources told ABC News in August. As chief of the FBI's counterespionage section, he helped oversee the FBI's investigation into Clinton's use of a private email server when she was the U.S. secretary of state. His office was also involved in investigating Russia's alleged efforts to influence last year's presidential election, including the hacking of Democratic National Committee computers. Strzok left the Mueller team amid revelations that he and a fellow, former team member, Lisa Page, had exchanged numerous texts during the 2016 election disparaging then-candidate Trump.

Lisa Page, described as a trial attorney with “deep experience [in] money laundering and organized crime cases,” left around the same time as Strzok and returned to work in the office of the FBI’s general counsel, a spokesperson for the special counsel confirmed to ABC News last September. According to one source, Page joined Mueller’s team on a short, temporary assignment and always expected to return as soon as that assignment ended. Page and Strzok remain under scrutiny for the text messages the two exchanged during the campaign.
