Amanda Rubio, the eldest of Marco Rubio's four children, was injured in a golf cart accident on Saturday.

"The family is grateful for all the messages of support and the prayers said for their daughter," Conant said Sunday.

The senator’s daughter had been visiting with classmates in a private community, and had been a passenger in a golf cart that was involved in the crash.

Marco Rubio spent much of the day campaigning with the GOP nominee for president, Mitt Romney, appearing at stops in Pensacola and Kissimmee. Rubio was informed of his daughter’s accident as he was leaving the stage in Kissimmee, and was en route to Miami on Saturday evening.

According to media reports, Romney’s motorcade pulled over in Central Florida around 7 p.m. to let Rubio off. The senator left in a police car.
