Evangelist Billy Graham has died at age 99.

He preached to more people than any other Christian evangelist in history: More than 2 billion people attended his sermons or tuned in to his radio and TV broadcasts, according to his staff.

Over the years, Graham acted as adviser to U.S. presidents from Harry Truman to Donald Trump, counseling them in their -- and the country's -- darkest hours.

A family spokesperson said "America's Pastor" died of natural causes at home this morning.

The world's best-known evangelist, the Rev. Billy Graham, has died. He was 99.

From the gangly 16-year-old baseball-loving teen who found Christ at a tent revival, Graham went on to become an international media darling, a preacher to a dozen presidents and the voice of solace in times of national heartbreak. He was America's pastor.

Graham retired to his mountain home at Montreat, N.C., in 2005 after nearly six decades on the road calling people to Christ at 417 all-out preaching and musical events from Miami to Moscow. His final New York City crusade in 2005 was sponsored by 1,400 regional churches from 82 denominations.
