Residents of Moore, Okla, are searching for survivors and coming to terms with a massive tornado that left more than 50 people dead and injured more than 200 others Monday afternoon.

Both the former IRS commissioner who was in charge when the agency singled out some conservative groups for extra scrutiny and the man who replaced him will be appearing at a Senate Finance Committee hearing Tuesday morning.

Douglas Shulman, an appointee of President George W. Bush who left the IRS last November, and acting commissioner Steven Miller (who is losing his job because of the scandal) are due at the 10 a.m. ET hearing.

Giant technology firm Apple is paying billions of dollars less than it should in U.S. taxes each year, according to a report by the Senate Permanent Subcommittee on Investigations. In a hearing Tuesday in Washington, D.C., Apple CEO Tim Cook will defend the company.

The subcommittee's report says Apple avoids the tax payments mainly by shifting profits to three subsidiary companies in Ireland. The investigation found Apple is taking advantage of technicalities in U.S. and Irish tax laws to avoid paying any tax on a huge portion of its profits.

NBC News has put together a time-lapse video of the EF-4 tornado that tore through the southern suburbs of Oklahoma City, Okla.

As we told you in the live blog, the National Weather Service says it was at least an EF-4 tornado with winds in excess of 166 mph. The tornado stayed on the ground for 40 minutes and traveled 20 miles.

Although Oklahoma is a state where tornadoes are a fact of life, few days stand out like May 3, 1999.
