With President Obama’s announcement Saturday that he will seek Congressional approval to strike Syria, the Sunday shows will interview lawmakers about how the United States should respond to the the use of chemical weapons in Syria, previewing the debate ahead.

Senator John McCain, Republican of Arizona and a member of the Senate Armed Services Committee, will join CBS’s “Face the Nation.” Mr. McCain, Mr. Obama’s former presidential opponent, has been an outspoken advocate of intervention in Syria.

Also on the program will be Senator Tim Kaine, Democrat of Virginia and another member of the Senate Armed Services Committee, and Senator Saxby Chambliss of Georgia, ranking Republican on the Senate Intelligence Committee.

On NBC’s “Meet the Press,” two members of the Senate Foreign Relations Committee â€" Senator Robert Menendez of New Jersey, who chairs the committee, and Senator Rand Paul, Republican of Kentucky â€" will share their thoughts on Syria.

Senator Jack Reed, Democrat of Rhode Island, and Senator James M. Inhofe, Republican of Oklahoma, are scheduled to weigh in on “Fox News Sunday,” discussing whether there is Congressional support for a strike.

Representative Peter T. King, Republican of New York and a member of the House Intelligence Committee, and Mike Baker, a former Central Intelligence Agency officer, will also join Fox to talk about the latest revelations from Edward J. Snowden.

Representative Eliot Engel of New York, ranking Democrat on the House Foreign Affairs Committee, and Representative Scott Rigell, Republican of Virginia and a member of the House Armed Services Committee, will appear on CNN’s “State of the Union.” Senator Chris Murphy, Democrat of Connecticut, who is hesitant about military intervention in Syria, will also appear on the program.

ABC’s “This Week” will include interviews with Gen. James E. Cartwright, a former vice chairman of the Joint Chiefs of Staff, and Vali Nasr, a former senior State Department adviser and dean of the Johns Hopkins School of Advanced International Studies.

In addition to NBC, Mr. Menendez will appear on Univision’s “Al Punto” at 10 a.m. Eastern and Telemundo’s “Enfoque” at noon Eastern. Otto J. Reich, a former ambassador, will also join Telemundo to talk about Syria.

Thomas J. Donohue, president of the U.S. Chamber of Commerce, will join C-Span’s “Newsmakers” to talk about policy issues including immigration and jobs.

William S. Cohen, former defense secretary, was interviewed about Syria on Bloomberg’s “Political Capital,” which aired Friday with repeats throughout the weekend. Richard L. Trumka, president of the A.F.L.-C.I.O., also appeared on the program to talk about organized labor.

Mary Cheney Criticizes Her Sister on Same-Sex Marriage

Mary Cheney, the younger sister of Liz Cheney, a Wyoming Senate candidate, sharply criticized her sister’s stance on same-sex marriage and urged her own Facebook friends to share the message.

Posting on Facebook on Friday evening, Mary Cheney, who is gay and married her longtime partner last year, wrote: “For the record, I love my sister, but she is dead wrong on the issue of marriage.”

Their father, former Vice President Dick Cheney, supports same-sex marriage, and the younger Cheney echoed some of his language on the issue when she added, “Freedom means freedom for everyone.”

“That means that all families â€" regardless of how they look or how they are made â€" all families are entitled to the same rights, privileges and protections as every other,” Mary Cheney wrote.

Earlier Friday, Liz Cheney revealed her position on same-sex marriage, a topic she has kept relatively quiet about since declaring her candidacy in July against incumbent Senator Mike Enzi, Republican of Wyoming.

“I am not pro-gay marriage,” Liz Cheney said in a statement responding to an apparent push poll against her in Wyoming. “I believe the issue of marriage must be decided by the states, and by the people in the states, not by judges and not even by legislators, but by the people themselves.”

That position â€" deferring to the will of the voters on a state-by-state basis â€" may represent something of a compromise between total support or opposition. But it did little to placate her sister.

“It’s not something to be decided by a show of hands,” Mary Cheney wrote.

And to emphasize that she was not shying away from drawing attention to her view, Mary Cheney concluded her Facebook post: “Please like and share if you agree.”

In an e-mail, Mary Cheney declined to comment further on her sister’s position, saying she would let her Facebook post speak for itself.

The Cheney family dispute mirrors the broader disagreement among Republicans on same-sex marriage. Less than a decade after George W. Bush and Dick Cheney won re-election in part thanks to conservative enthusiasm over enshrining traditional marriage into law, some in the party believe they are losing voters, particularly younger ones, over an issue on which public opinion has changed rapidly. But other Republicans believe traditional marriage is a pillar of family values, and in some cases are reluctant to abandon their social conservative base on the issue.

Liz Cheney’s stance underlines the degree to which full-throated support for same-sex marriage, even in a libertarian-leaning state like Wyoming, still poses a political risk in a Republican primary.

Mr. Enzi opposes legalizing same-sex marriage.
