President Obama got no questions about Iraq or Afghanistan in last night’s press conference, but was asked if the raging violence of drug cartels in Mexico is “a national security threat.” Guest host Lawrence O’Donnell explores the new tensions in US relations with Mexico and what the Obama Administration hopes to achieve with Secretary of State Hillary Clinton’s meeting today with Mexican President Felipe Calderón.  Also, Obama meets with Senate Democrats on the budget, and Hillary: The Movie confuses the Supreme Court.
