President Obama will participate this morning in the groundbreaking of the Smithsonian National Museum of African American History and Culture.
The museum, set to open in 2015, will be the only national museum devoted to African-American life, art and history.
The president will deliver remarks at a ceremony marking the start of the museum's construction, just blocks from the White House. Former first lady Laura Bush will also be in attendance.
The Obama administration will also release its corporate tax reform proposal today, calling for a cut in the top tax rate for corporations to 28 percent, from 35 percent.
The White House will propose paying for the overhaul by eliminating dozens of tax loopholes and subsidies, according to a senior administration official. The full details of the president's plan will be released by Treasury Secretary Tim Geithner later this morning.
