US President Barack Obama (R) and First Lady Michelle Obama (2nd-L) greet German Chancellor Angela Merkel (2nd-R) and her husband Joachim Sauer (L) at the North Portico of the White House in Washington, DC, on June 7, 2011 for the State Dinner. Obama warned Europe’s debt crisis must not destabilize the global economy, as he laid on a lavish and warm White House welcome for Merkel. Obama said he and Merkel had extensive talks about the plight of debt-stricken Greece, which needs a second huge financial bailout, despite some reluctance from some eurozone members to stump up fresh funds.
