The charter plane carrying former president Donald Trump’s running mate Sen. JD Vance (R-Ohio) made an emergency landing in Milwaukee after a door seal malfunction, the campaign said Friday.

The plane, a Boeing 737, declared an emergency shortly after it had left the airport in Milwaukee and returned for repairs, campaign spokesperson Taylor Van Kirk said in a statement. The issue was resolved, and the plane continued to Cincinnati, where Vance lives. Vance was in Milwaukee for a campaign event at the city’s police association.

The emergency landing comes a week after Trump’s plane was diverted as he headed to Montana for a rally last Friday.

Boeing has faced greater scrutiny for its assembly process of the 737 Max — the updated version of the older 737 model used by Vance — after an Alaska Airlines flight in January experienced a midair blowout leaving a hole in the fuselage.

Vance was traveling with his wife, his dog, campaign staff members and a traveling pool of reporters.
