House Speaker John Boehner, R-Ohio, assures his chamber "won't be stampeded" by the White House and Senate and will "work its will" on immigration legislation - but "don't ask me how," he added.

House Minority Leader Nancy Pelosi, D-Calif., asked reporters why it has become "politicized" that the IRS singled out conservative groups for excessive scrutiny, pointing out that Steven Miller, former acting director of the agency, was appointed by George W.

Rep. Stephen Lynch, D-Mass., says the IRS "stonewalled" congressional committees investigating the agency's targeting scandal, warning that if IRS officials are not more forthcoming, "You will leave us no alternative but to ask for the appointment of a special prosecutor...to get to the bottom of this."

While maintaining that the White House tries to provide information as "quickly as possible and as comprehensively as possible," press secretary Jay Carney, after more than a week of being battered by reporters for his halting disclosure of information related to various controversies, admitted, "There have been some legitimate criticisms about how we're handling this...And I say 'legitimate' because I mean it."

U.S. Secretary of Homeland Security g addressed the media in Moore, Okla., in the aftermath of the deadly tornado that tore through the city.
