White House Pledges Action as Oil From Spill Begins Hitting Land 29 Apr 2010 President Barack Obama today pledged "every single available resource" to plug an oil leak in the Gulf of Mexico, dispatching "SWAT" inspection teams to the rigs in the area and three top administration officials to oversee the response to the spill heading inexorably toward Louisiana's coast. Fingers of oily sheen from the massive slick, 600 miles in circumference and expanding, began lapping the shoreline late tonight, The Associated Press reported.
