From Fox News:

The top US immigration enforcement official acknowledged Thursday that the Obama administration has in fact released thousands of illegal immigrants from local jails over the last month despite prior claims that the release was only in the hundreds.

The sequester clemency:

Immigration and Customs Enforcement Director John Morton, at a House appropriations subcommittee hearing, said the agency released a total of 2,228 illegal immigrants from local jails “throughout the country” between Feb. 9 and March 1 for “solely budgetary reasons.”

But DHS Secretary Janet Napolitano says she knew nothing of this.  Of course.  She’s Sgt Schultz.
