President Barack Obama wants legislation in place overhauling financial regulations by the September two-year anniversary of the 2008 Wall Street collapse, Reuters quoted White House spokesman Robert Gibbs as saying today. Gibbs said Obama does not believe it is unrealistic to expect a bill could be on his desk by the end of May. "The president would like to see with his signature strong rules in place certainly by the two-year anniversary" of the cascade of events that prompted the Wall Street collapse, Gibbs told reporters.
