The event, according to Beck's website, is designed to honor "our heroes, our heritage and our future." It "pays tribute to America's service personnel and other upstanding citizens who embody our nation's founding principles of integrity, truth and honor."
"Our freedom is possible only if we remain virtuous," the site says. "Help us restore the values that founded this great nation."
In addition to himself and Palin, Beck says that Ted Nugent and Marcus Luttrell will appear at the rally, and that country artist Jo Dee Messina will perform. (Note: This story has been changed to reflect the fact that Gary Sinise is not planning to attend the event, according to his representatives. Beck had said Sinise would attend.)
He stresses that the event is not a Tea Party rally.
"There will be absolutely no politics involved," according to a release. "This rally will honor the troops, unite the American people under the principles of integrity and truth, and make a pledge to restore honor within ourselves and our country."
In a video promoting the rally on the Restoring Honor YouTube page, singer Krista Branch tells people to "leave your signs at home."
"Imagine hundreds of thousands of Americans gathering together to honor those in our military who fight to protect our freedoms," she says. "We will commit ourselves to the founding principles of faith, hope and charity. On that single day, with God's help, we will light a fire on this nation that will never be put out."

In a release today, the Brady Center To Prevent Gun Violence noted that the National Rifle Association placed an advertisement for the event outside its magazine First Freedom.
The Brady Center complained that the NRA, Beck and others involved with the rally are "using the anniversary and site of Dr. Martin Luther King's 1963 March on Washington."
Wrote Brady Campaign President Paul Helmke: "Are Glenn Beck, Sarah Palin, the NRA's Wayne LaPierre...at this place and time, the new keepers of King's dream and of Lincoln's legacy? Or do they, with this event at this place and time, in one of the boldest and most public ways imaginable, mock, and indeed, slander, everything for which these men so nobly stood, and for which they died?"
