Bill Stepien

Two months after losing Christie's confidence, Stepien made a "soft landing" at the data and phone bank giant FLS Connect, which hired him to work on sales and strategy. Stepien then received a subpoena to submit documents to the New Jersey Legislature panel investigating in the lane closures. In a 19-page letter sent to Reid Schar, special counsel to the joint Senate and Assembly committee, Stepien's lawyer cited Stepien’s Fifth Amendment privilege against compelled self-incrimination, noting that in addition to the legislative probe, a federal criminal inquiry into the lane closures was also underway.

In 2019, Stepien, along with Trump, worked to convince New Jersey Democratic congressman Jeff Van Drew to switch to the Republican Party amid the Impeachment of Donald Trump. In December 2019, Van Drew hired Stepien as an adviser to his 2020 re-election campaign.

In August 2016 Stepien was hired to work for the Donald Trump presidential campaign, 2016. Stepien was named the White House political director on January 20, 2017. In December 2018, Stepien and White House Director of Public Liaison Justin Clark were named Senior Political Advisors to the President's re-election campaign focusing on delegate and party organization.

After Donald Trump secured the Republican nomination, he joined the presidential campaign in August 2016 and was later named the White House political director during the Trump presidential transition.

In the trial in September 2016 about the lanes closures, federal prosecution witness David Wildstein said that Stepien was aware of the lane closures as they were happening.

On January 7, 2014, Christie announced that he wanted Stepien to take over the chairmanship of the New Jersey Republican Party from Sam Raia. On January 7, 2014, Christie said, "I’ve asked Bill Stepien to be our new State Party Chairman because no one better understands how to grow our party, communicate our message and, most importantly, win elections... Bill Stepien is the best Republican operative in the country, and New Jersey Republicans will be fortunate to have him leading our Party."

Stepien's firm, Nassau Strategies LLC, is based out of a residential home on Knob Hill Road in Washington Township, Morris County, New Jersey. The firm benefited from Christie's chairmanship of the Republican Governors Association, as did many other New Jersey-based consulting firms. In December 2013, the RGA paid Stepien's firm $15,000, just a month before Christie cut ties with Stepien. On December 8, 2014, GOPAC made a retainer payment of $6,000 to Nassau Strategies for political strategy consulting.

Investigators eventually discovered that Stepien was in a romantic relationship with Bridget Kelly, his replacement as Christie's deputy chief of staff. Their relationship lasted until August 2013, as the plan to close the lanes was being implemented. Though their personal relationship was over, Stepien was kept abreast of the lane closures and the intended fallout. It was the emails between Stepien and those involved in the lane closures that sealed his fate. Christie said, "I was disturbed by the tone and behavior and attitude of callous indifference that was displayed in the emails by my former campaign manager, Bill Stepien."

Stepien served as campaign manager in Chris Christie's successful campaign for Governor of New Jersey in 2009. Christie's first major announcement after winning the election was the naming of four top staffers, including Stepien as a Deputy Chief of Staff for Legislative and Intergovernmental Affairs. In April 2013, Stepien resigned from that position to become the manager of Christie's re-election campaign. His replacement as Deputy Chief of Staff for Legislative and Intergovernmental Affairs was Bridget Anne Kelly.

Stepien served as Political Director of the 2004 Bush/Cheney campaign in New Hampshire, and as Director of the Republican National Committee's 72-Hour Campaign in 2005 and 2006. In 2008, he was a Regional Campaign Manager for Senator John S. McCain's presidential campaign before serving as National Field Director, a role in which he also served for New York Mayor Rudy Giuliani's presidential campaign in 2007-08. He also served in the same role for Presidential hopeful Donald Trump in the 2016 Presidential Campaign.

Stepien began his political career working on Anthony Bucco's 1997 State Senate campaign, and on Bob Franks' 2000 U.S. Senate race. He worked for Public Opinion Strategies and DuHaime Communications before managing Bill Baroni's 2003 bid for New Jersey State Assembly—the only Republican to oust a Democratic incumbent that year, and one of PolitickerNJ.com's Best Campaigns of the Year.

Bill Stepien (born 1978) is a Republican political operative and former White House political director in the Trump administration. Stepien managed both of Chris Christie's gubernatorial campaigns and served as his Deputy Chief of Staff before being fired in 2014 after Christie said he "lost confidence" in Stepien's judgment.
