There will be a ceremony at 4 PM Central Time today (Monday the 3rd) honoring President Bush. You can watch it below when it goes live.
Here is the official Press Release with the details:
The late President George H.W. Bush will lie in state in the United States Capitol Rotunda from today through Wednesday morning. At 5:00 p.m. ET, the Bush family and friends, the vice president, members of Congress, and members of the administration will gather for a service honoring President Bush. At 7:30 p.m. ET, the Rotunda will open to members of the public so they may pay their respects.
The Capitol service will include eulogies by the vice president, speaker, and Senate majority leader. Congressional leadership and the vice president will participate in the laying of wreaths.
President Bush lived an exemplary life of service to this country. The last president to serve in combat, he served as a pilot in the United States Navy in World War II, flying more than 50 combat missions and earning a Distinguished Flying Cross. He spent decades as a public servant, beginning in the House of Representatives and serving as ambassador to the United Nations, envoy to China, director of Central Intelligence, and vice president. He was the dedicated husband of 73 years to the late First Lady Barbara Bush and the patriarch of the Bush family.
Lying in state is a rare honor authorized by Congress and given to those who have devoted their lives to military or public service to our nation. Just 27 individuals have lain in state or in honor in the Capitol, with the most recent being late Senator John McCain following his passing earlier this year. Congress has also honored the unknown soldiers of World War I, World War II and the Korean War, and of the Vietnam Era. President Bush’s casket will lay upon the catafalque constructed in 1865 to support that of President Abraham Lincoln as he laid in state in the Rotunda.
