Obama to make televised speech from Afghanistan at 7:30 p.m.

— -- President Barack Obama, on an unannounced trip to Afghanistan, will make a televised speech from Bagram Air Base at 7:30 p.m. ET Tuesday. Yahoo News will stream the speech live and will provide updated coverage of the president's remarks.

Obama, whose secrecy-shrouded trip came on the one-year anniversary of the raid that killed Osama bin Laden, met in Kabul with Afghan President Hamid Karzai. The two leaders signed a long-term partnership agreement that governs the United States' role in Afghanistan after NATO-led combat forces leave in 2014. NATO leaders are due in Chicago in late May for a summit at which they are expected to spell out how the alliance's troops will hand over security duties to Afghan security forces throughout 2013.

Obama's trip also carried a strong political flavor: He has been using the May 1, 2011 bin Laden raid to pummel presumptive Republican presidential nominee Mitt Romney.
