Internal Revenue Service Commissioner John Koskinen will testify before the House Oversight Committee on Monday at 7 p.m. about the missing Lois Lerner emails in response to a subpoena.

The IRS has said that the a hard drive crash resulted in the loss of nearly two years' worth of Lois Lerner's emails from January 2009 to April 2011. But Republicans argue the agency's claim is an excuse to hide emails critical to their probe of improper scrutiny of conservative nonprofits applying for tax-exempt status.

Three House committees will discuss the surge of child migrants crossing the Mexican border into the U.S.  

On Tuesday, the House Homeland Security Committee will hear testimony from Federal Emergency Management Agency Craig Fugate and Homeland Security Secretary Jeh Johnson.

Then on Wednesday, the House Judiciary Committee will hold a hearing with officials from Immigration and Customs Enforcement and Customs and Border Protection expected to testify.
