Teamsters President James Hoffa has been elected to succeed his brother during a tumultuous time for the union.
The 88-year-old, a justice of the peace in Michigan, will continue the family tradition after 86 years as a union leader.
James Hoffa Jr took over from his brother after his death in 2017.
His term ends in 2023. Teamsters General Council Bill King will serve as vice-president for three years.

In a statement on Friday, Hoffa said: “It has been a thrilling and amazing ride to lead the Teamsters union for the past four years.
“While the biggest challenges are yet to come, I have vowed to take care of those I have left behind, while using the experience I have garnered as the Teamsters president to guide my future.
“This is my last four years as Teamsters president, but I will continue working with all members and loyal supporters to do everything we can to achieve the goals and objectives we have set as a union.”
Under Jimmy Hoffa’s leadership, the Teamsters governed metal packers, railroads, auto parts, mail carriers and more.
He was instrumental in negotiating the first $30 (£25) minimum wage in the US, won concessions for freight drivers and shook off threats of bankruptcy, more than 80 years ago.
Despite a reputation as an intimidating and bitter old-guard union leader, Jimmy Hoffa Jr won respect among younger union members and became known as a peace-loving uncle figure.
His son, who spent time in prison for corruption while operating a trucking company, decided to run for president last year rather than become the third generation of family to run the Teamsters.
Throughout his five terms, Jimmy Hoffa Jr spearheaded the Teamsters’ investments in technology and drivers trained for new trade sectors.
His biggest challenge came in September 2016, when new state legislation in Michigan forced the forced retirement of tens of thousands of senior Teamsters, largely those who worked for the American Motors Corporation.
As one of only two unions not covered by state retiree healthcare reform, the Teamsters were left with a huge liability.
That bill and Jimmy Hoffa Jr’s own health problems saw his re-election campaign beaten in 2017, by longtime rival King.
