Robert O’Neill scoffed at the notion that Joe Biden could bring any type of change to Washington, D.C., after spending most of his life in public office.

Biden, 77, was first elected to the U.S. Senate in 1973, where he represented the state of Delaware for 36 years, only leaving his seat to spend eight years in the White House as President Barack Obama’s vice president. The former vice president took two years off from holding down a job in Washington before announcing his third presidential bid in April.

In a tweet posted Sunday, O’Neill mocked the idea that Biden could be the change he promises for Washington, D.C. “[Joe Biden] was a politician in D.C. for 44 years. But if elected, he’s gonna change Washington…” O’Neill tweeted.

O’Neill, 43, was a member of SEAL Team 6, the group that found and killed al Qaeda leader Osama bin Laden. The Navy SEAL has made a habit of roasting politicians on Twitter, including his jab at 2020 Democrats, such as California Rep. Eric Swalwell, for spending more time outlining their plans to give healthcare to illegal immigrants than they did discussing veteran homelessness.

Although he typically jabs Democrats online, O’Neill has noted that the mission to kill bin Laden was a “bipartisan effort,” adding, “We all wanted to get him as soon as we could.”
