Democratic presidential hopeful Pete Buttigieg on Thursday hammered President Trump for saying he had bone spurs to avoid being drafted into the Vietnam War, accusing him of faking the disability.

“Well, I have a pretty dim view of his decision to use his privileged status to fake a disability in order to avoid serving in Vietnam,” Buttigieg, an Afghanistan War veteran, said during a livestreamed interview with The Washington Post.

The South Bend, Ind., mayor has shot to national prominence in recent months following a media blitz that has included various interviews with national outlets as well as more niche publications.

Buttigieg, who is competing against more than 20 other Democrats for the party’s presidential nomination, has also gone after Vice President Pence, suggesting he held homophobic views and hitting his tenure as Indiana governor, claims the vice president has rejected.

While still polling well behind front-runners such as former Vice President Joe Biden and Sen. Bernie Sanders (I-Vt.), Buttigieg has risen in national and statewide polling and has raked in millions of dollars in campaign donations.

Democrats have criticized Trump over his claims of bone spurs to avoid the Vietnam War draft since he began campaigning for president in 2015.

Trump defended his medical claim in 2016, telling The New York Times a doctor “gave me a letter — a very strong letter on the heels” to give to draft officials.

Reports later emerged that a New York podiatrist may have given Trump the diagnosis as a favor to Trump’s father.
