Advocates reacted angrily Wednesday to President Obama's refusal to use executive action to halt deportations of unauthorized immigrants, as frustration over the delay of immigration legislation began to blow back to the White House.

Shortly after 10:15 a.m., seven undocumented workers handcuffed themselves to the north gates of the White House, unfurling a sign with Obama's image and the words: "Mr. President Stop Deportations". They chanted "not one more!" and "si se puede," a Spanish phrase that roughly translates to "yes we can," Obama's 2008 campaign slogan.
