Former President Gerald Ford has passed away:

"My family joins me in sharing the difficult news that Gerald Ford, our beloved husband, father, grandfather and great grandfather has passed away at 93 years of age," former first lady Betty Ford said in a brief statement issued from her husband's office in Rancho Mirage. "His life was filled with love of God, his family and his country."

He died at 6:45 p.m. Tuesday at his home in Rancho Mirage, about 130 miles east of Los Angeles, his office said in a statement. No cause of death was released. Funeral arrangements were to be announced Wednesday.

Ford had battled pneumonia in January 2006 and underwent two heart treatments _ including an angioplasty and a pacemaker implant _ in August at the Mayo Clinic in Rochester, Minn.

"The American people will always admire Gerald Ford's devotion to duty, his personal character and the honorable conduct of his administration," President Bush said in a statement Tuesday night. "We mourn the loss of such a leader, and our 38th president will always have a special place in our nation's memory."
