While the telethon will be helping Harvey's victims, "by Tuesday we might be helping more than them", Braun said, a reference to powerful Hurricane Irma in the Atlantic Ocean, which may threaten Florida and the southern USA this weekend.
The telethon will come from three locations: Universal Studios lot, Times Square and Nashville's Grand Ole Opry with country star George Strait being beamed in from the Majestic Theater in San Antonio, Texas.
A star-studded benefit concert and telethon will be simulcast across multiple networks to raise money for Hurricane Harvey relief.
