ABC News/The United States Senate

As second-term scandals engulf the White House, Obama senior adviser Dan Pfeiffer goes one-on-one with George Stephanopoulos, Sunday on "This Week."

Controversy consumed Washington this week, with bipartisan outrage over the revelation of the IRS' scrutiny of conservative groups and the Justice Department obtaining AP phone records in a leak investigation, plus lingering questions about the response to Benghazi. As the White House fights back against the growing scandals, how will they threaten President Obama's second term agenda? How far will these scandals reach - and how far will Republicans take their challenges to the Obama administration?

Obama senior adviser Dan Pfeiffer responds to the White House's rough week, Sunday on "This Week."

Plus, key lawmakers on both sides of the aisle - Sen. Bob Menendez, D-N.J., Sen. Rob Portman, R-Ohio, Rep. Tom Price, R-Ga., and Rep. Charles Rangel, D-N.Y., - debate the fallout from the IRS, Benghazi, and AP leak investigation scandals, only on "This Week."

Then, the "This Week" powerhouse roundtable takes on all the week's politics, with ABC News' George Will; National Journal Editorial Director Ron Fournier; American Urban Radio Networks White House Correspondent April Ryan; editor and publisher of The Nation Katrina vanden Heuvel; and ABC News Senior Washington Correspondent Jeff Zeleny.
