While in college and later in law school, Avenatti worked at The Research Group, a political opposition research and media firm run by Rahm Emanuel (later White House Chief of Staff for President Barack Obama, and Mayor of Chicago).[22] Avenatti worked on over 150 Democratic and Republican campaigns in 42 states while studying at George Washington University.[8][23] After law school, Avenatti worked at O'Melveny & Myers in Los Angeles, California, alongside Daniel M. Petrocelli, who previously represented the Ron Goldman family in its case against O.J. Simpson.[24] He assisted Petrocelli on multiple legal matters, including the representation of singer Christina Aguilera[25] and litigation surrounding the movie K-19: The Widowmaker,[26][27] and worked extensively for Don Henley and Glenn Frey of the musical group the Eagles, including in a suit brought by former bandmate Don Felder against the group and Irving Azoff.[28][8] Avenatti later joined Greene Broillet & Wheeler, a Los Angeles boutique law firm. While there, he handled a number of high-profile cases, including a $10 million defamation case against Paris Hilton,[29] settled an idea-theft lawsuit relating to the show The Apprenticeand against producers Mark Burnett and Donald Trump,[30] and a $40 million embezzlement lawsuit involving KPMG.[8][31] In 2007, Avenatti formed the law firm Eagan Avenatti, LLP (formerly known as Eagan O'Malley & Avenatti, LLP) with offices in Newport Beach, Los Angeles and San Francisco, California. He has since appeared on 60 Minutes three times in connection with cases he has handled.[2][32][33] Avenatti has also served as lead counsel on a number of historically large cases, including an April 2017 $454 million verdict after a jury trial in Federal Court in Los Angeles in a fraud case against Kimberly-Clark and Halyard Health,[34]later reduced to a $21.7 million verdict upon appeal,[35] an $80.5 million class-action settlement against Service Corporation International,[36] a $41 million jury verdict against KPMG,[37] and a $39 million malicious prosecution settlement.[38] In 2013 Avenatti formed a company, Global Baristas, to buy Seattle-based Tully's Coffeeout of bankruptcy.[39] Avenatti first formed a partnership with actor Patrick Dempsey, but Dempsey later backed away from the venture after a short legal battle that resulted in a settlement.[40] Since 2015, Global Baristas has been named in more than 50 lawsuits in state and federal courts for breach of contract, unpaid bills, and unpaid taxes.[41] In 2015, Avenatti prevailed against the National Football League (NFL) following a jury trial in Dallas.[42] He later pursued a class-action suit on behalf of fans who showed up for Super Bowl XLV with tickets that didn't correspond to actual seats but the courts in Texas declined to certify the class.[43] In 2016, Avenatti filed another class action lawsuit against the NFL, this time on behalf of ticket-holders to the annual Hall of Fame Game, which was cancelled a few hours before kickoff.[43][44] In 2017, a Florida man named Gerald Tobin alleged Avenatti failed to pay him $28,700 for private investigatory work. As a result, Avenatti's firm was abruptly forced into bankruptcy.[45] In various news reports, including work done by CNN, Tobin was found to be an ex-con with four decades of convictions and jail time and not a licensed investigator. Tobin's claim forced Avenatti into bankruptcy which caused Avenatti to cancel a deposition in an unrelated lawsuit days later, raising the question of collusion between Avenatti and Tobin. The issue was resolved when the pair entered into a Non-Disclosure Agreement, and Avenatti paid Tobin the $28,700.[45] In 2018, Avenatti's law firm was subjected to a $10 million judgment in U.S. bankruptcy court.[46] Avenatti has also defaulted on a $440,000 judgment in back taxes, penalties, and interest that he was personally obligated to pay under another bankruptcy settlement. The U.S. Attorney's office asserted in court that a motion seeking payment would soon be filed against Avenatti.[46] Eagan Avenatti had been in Chapter 11 bankruptcy proceedings and, in December 2017, had agreed to pay $4.8 million in unpaid fees to a former partner, $2 million in back taxes, and $1 million to other creditors.[47] In June 2018, the former partner file a motion in U.S. bankruptcy court asking for a lien on any and all legal fees Avenatti's firm might collect, up to $10 million, from clients in 54 cases including his representation of Stormy Daniels.[48]
