Democratic presidential candidate John Kerry (search) plans to take time off from the campaign trail to observe Ronald Reagan's (search) death.

Kerry plans to offer a tribute to Reagan at a high school graduation in Ohio Sunday. He canceled a trip to Denver Sunday night to return to Washington, where Reagan's body is to be flown.

Spokesman David Wade says it hasn't been determined when the candidate will resume his schedule. Kerry had planned to give a speech in Denver Monday morning, then travel to Los Angeles for a star-studded fund-raiser at the Walt Disney Concert Hall (search).

Kerry says Reagan lived by the noble ideal of bipartisanship, noting, "He was our oldest president, but he made America young again."
