Party Majority PAC, a political committee founded by Hillary Clinton-aligned Democratic operative Adam Parkhomenko, provides support for two major projects, “Kremlin Annex,” and “Moscow Mitch.”
Party Majority PAC provided funding for the campaign of now-U.S. Representative Donna Shalala (D-FL) in a 2018 Florida congressional race. Organizations in the past founded by Adam Parkhomenko have been accused of colluding with candidates despite restrictions not to do so by the Federal Election Commission.
After the release of Special Counsel Robert Mueller’s report on foreign interference in the 2016 Presidential election, Democratic operatives made unsubstantiated “collusion” allegations against Senate Republican Leader Mitch McConnell (R-KY) through a project called “Moscow Mitch.” Adam Parkhomenko used the phrase “Moscow Mitch” through a Party Majority PAC fundraising scheme and purchased the domain name MoscowMitch.com.  Parkhomenko used proceeds from the campaign to pay for digital billboards in California at a McConnell fundraiser.
In 2018, Party Majority PAC raised $300,000, but only $85,000 went towards other political committees or independent expenditures for Democratic candidates. 
Protests of Brett Kavanaugh
In October of 2018, Party Majority PAC organized the event “Bravery is Contagious” to protest the nomination of then-Judge Brett Kavanaugh to the U.S. Supreme Court. The website for the event listed a number of prominent liberal celebrities endorsing the protest, with possible appearances by Lena Dunham, Whoopi Goldberg, Maggie Gyllenhaal, John Legend, and Esperanza Spalding. At the same time, the FBI was completing an investigation into allegations of sexual misconduct against Kavanaugh from his time in high school. 
Party Majority PAC founder Adam Parkhomenko is a long-time Democratic operative and supporter of Hillary Clinton. Parkhomenko founded “Ready for Hillary” (later “Ready PAC”) that supported Clinton’s 2016 campaign; FEC complaints alleged that the PAC improperly coordinated with Clinton’s official campaign following a payment of $135,000 from Ready for Hillary PAC to Friends of Hillary for a one-time use of an email list. Allegations of misconduct were dismissed in 2019 on a split vote by the FEC. 
Adam Parkhomenko, when founding Ready for Hillary, received assistance from former Clinton strategist Harold Ickes, former Clinton White House political director Craig Smith, and Hillary Clinton campaign lawyer Jim Lamb. Parkhomenko also received assistance from longtime Clinton aide James Carville. 
Party Majority PAC was created to coordinate at the national and state levels with the Democratic Party. Additionally, out of a frustration of non-coordination, Party Majority PAC is meant to assist in the non-communication between Democratic Party assets. 
In 2018, Party Majority PAC spent $40,622 in support of Donna Shalala, a Democratic candidate for Congress in Florida who had served as Health and Human Services Secretary in the Clinton administration, and $20,614 in opposition to her primary challenger, former State Representative David Richardson (D-Miami). 
The “Moscow Mitch” project is designed to defeat Senator Mitch McConnell (R-KY) as Majority Leader in the U.S. Senate by tying Republican members to McConnell.
