President-elect Joe Biden is expected to pick former South Bend, Indiana, mayor Pete Buttigieg to head the Transportation Department, according to three people familiar with the plans.

Buttigieg, one of Biden’s rivals for the Democratic presidential nomination, was a breakout star of the primaries, sharing victory in the nation’s first caucus with Bernie Sanders. He suspended his campaign before Super Tuesday and endorsed Biden.

Biden has compared the 38-year-old Buttigieg to his late son, Beau.

“To me it’s the highest compliment I can give any man or woman. And, like Beau, he has a backbone like a ramrod,” Biden said during the March event, as Buttigieg stood behind him, bowing his head. “I promise you, over your lifetime, you’re going to end up seeing a hell of a lot more of Pete than you are of me.”

The three people confirmed the news to The Associated Press on condition of anonymity because they didn’t want to publicly preempt the president-elect’s announcement.

Buttigieg is the former mayor of Indiana’s fourth largest city, serving from 2012 to 2020. He also served a seven-month deployment as an intelligence officer in Afghanistan.

The Transportation Department helps oversee the nation’s highway system, planes, trains and mass transit and is poised to play a key role early in the incoming administration.

Biden has pledged to spend billions making major infrastructure improvements and on retrofitting initiatives that can help the U.S. battle climate change. He also wants to immediately mandate mask-wearing on airplanes and public transportation systems to slow the spread of the coronavirus.

Infrastructure spending can be a bipartisan issue, and President Donald Trump spent years promising to push a major bill through Congress that never materialized. Instead his administration moved to soften carbon emissions standards that Biden’s team will likely work to undo as part of the broader commitment to slowing global warming.

The once most frequently mentioned early pick to head the Transportation Department, President Barack Obama’s former chief of staff and ex-Chicago Mayor Rahm Emanuel, sparked strong pushback from top progressive activists. Emanuel, also a former congressman, helped oversee the Obama administration’s distribution of tens of billions of dollars in transportation spending as part of a massive stimulus bill approved following the financial crisis — but now seems unlikely to take any position in Biden’s administration.

His chances faded after progressives and civil rights leaders were very critical of Emanuel’s handling of the high-profile police shooting death of Laquan McDonald, a Black teenager killed by a white officer, during his time as Chicago’s mayor.
