Sunday Talks, 4/22/12

The Secret Service scandal in Colombia dominates this Sunday’s television talk shows, as the Republican presidential race turns to the field of possible running mates for the likely nominee, Mitt Romney.

“Fox News Sunday” and CBS’s “Face the Nation” have Sen. Joe Lieberman (I-Conn.), chairman of the Senate Homeland Security and Governmental Affairs Committee, which is investigating reports that Secret Service agents and military personnel were involved with prostitutes ahead of President Barack Obama’s trip to Colombia for the Summit of the Americas.

Reps. Peter King (R-N.Y.), chairman of the House Homeland Security Committee, and Darrell Issa (R-Calif.), chairman of House Oversight and Government Reform Committee, are on NBC’s “Meet the Press” to discuss the Secret Service scandal, as well as the inquiry into alleged lavish spending by officials of General Services Administration.

CBS also has a roundtable discussion on the Secret Service scandal with former Secret Service Director W. Ralph Basham, Rep. Sheila Jackson Lee (D-Texas), Rep. Elijah Cummings (D-Md.) and Sen. Tom Coburn (R-Okla.).

Cummings is also on CNN’s “State of the Union” and TV One’s “Washington Watch.”

ABC’s “This Week” has Maine Sen. Susan Collins, the ranking Republican on Lieberman’s committee, and Jackson Lee.

And Keith Olbermann makes his first TV appearance since his split with Al Gore’s Current TV, joining an ABC roundtable discussion with Wall Street Journal columnist Peggy Noonan and ABC’s George Will, Donna Brazile and Matthew Dowd.

NBC has as well the president’s senior campaign strategist, David Axelrod, who also stops by CNN.

Additionally on CNN, Sen. Marco Rubio, (R-Fla.), often mentioned as a possible Romney running mate, discusses the presidential campaign and immigration issues.
