KNOXVILLE, Tennessee (AP) -- Vice President Dick Cheney was heckled by peace protesters Tuesday as he spoke at the groundbreaking for a public policy center honoring former Senate Majority Leader Howard Baker.During Cheney's remarks, about a half-dozen people protesting the war in Iraq yelled, "War, what is it good for?" and held up a large banner saying, "Peace Now."Cheney continued speaking and didn't acknowledge the protesters, who were escorted from the ceremony inside the University of Tennessee's basketball arena.About 50 protesters, most of them appearing to be college age, demonstrated outside. Several carried signs, including one that read "Honor Baker, Impeach Cheney."Cheney during the event lauded Baker, a Republican who was President Reagan's chief of staff and ambassador to Japan."It's good to know that far into the future people will come to this place and learn of Howard's career and his deep belief in the nobility of public service," Cheney said.About 400 people attended the ceremony, which coincided with Baker's 80th birthday.Asked about the Bush administration's handling of the Iraq war, Baker said he doubts there was "something sinister and significant that would be uncovered by a closed session" of the Senate on the buildup to the war."It is almost always the cover-up rather than the event that causes trouble, and I see no evidence of a cover-up here," added Baker.He is still remembered for posing a key question during the 1973 Watergate hearings that rocked the Nixon White House: "What did the president know and when did he know it?"The $25 million privately financed Baker Center is being created to foster greater appreciation of public service and greater understanding of government.Copyright 2005 The Associated Press.
