Anderson told the Salt Lake Tribune he hoped the demonstration would be "the biggest ... this state has ever seen," to protest Bush's appearance before a gathering of the Veterans of Foreign Wars.
"This administration has been disastrous to the country," he said. "If people could organize and speak out in an effective manner from the reddest state in the country, that would garner a lot of attention."
Mike Parkin, a local VFW official, objected to Anderson's plan.
"It makes the mayor look very, very unpatriotic," said Parkin. "It makes him look despicable."
Anderson said the demonstration itself would be patriotic.
"Patriotism demands that people speak out when we see our government officials acting in such anti-democratic and deceitful ways to the people of our country," he said.
