Amid Sen. John McCain s (R-Ariz.) battle with brain cancer, the 81-year-old reportedly wants President Donald Trump to stay away from his funeral.

Friends of the Vietnam war veteran and 2008 presidential candidate, who has had a rocky relationship with Trump, asked the White House that they send Vice President Mike Pence instead, The New York Times and NBC News reported on Saturday.

The service is planned for Washingtons National Cathedral and will have eulogies read by former Presidents Barack Obama and George W. Bush, a source close to McCain told NBC News.
