Television evangelist Pat Robertson, who has rattled the religious and political establishment with recent controversial declarations, acknowledged Thursday that "my passion runs ahead of me" on some occasions. "I've been doing TV for years and years," Robertson said. "And the problem is, I ad lib." Interviewed on ABC television's "Good Morning America" on the morning of the annual National Prayer Breakfast, Robertson was asked about statements suggesting that the United States assassinate President Hugo Chavez of Venezuela and intimating that Prime Minister Ariel Sharon's stroke was God's punishment for giving up the Gaza strip. Robertson sent a letter to Sharon's family apologizing for his remark about the Israeli leader.
