Bob's Blog: Hot-button issues dominate Washington

In a 5-4 ruling, the Supreme Court invalidated a section of the Voting Rights Act of 1965 that required states to get approval from the federal government before changing election laws; and, a rare disease has affected dozens of members of the same family in eastern Iowa.

This has been a week of historic proportion in Washington.

The immigration debate came to a head yesterday when the Senate passed a comprehensive bill with strong bipartisan support. Immigration advocates who have fought long and hard for this bill earned their victory, but their celebration is about to get cut short as the measure moves to the House of Representatives.

House Republicans, the majority of them, do not want comprehensive immigration reform. Republicans are just not together on this - particularly the House members who live in districts where they do not have an overwhelmingly large Hispanic population. They'll vote against immigration reform with ease. They know to tread carefully and vote "no," or else the party will find a primary opponent for 2014.

With this divide between the Senate and House, it's a real long shot that a comprehensive bill lands on President Barack Obama's desk. You can go through all the details and the back-and-forth between the two sides but there still isn't a clear Republican majority in the House to pass the bill.

Even after months of rigorous debate, I think we'll have to unfortunately write the same bottom line for immigration reform that we've written for so many other issues in the past year: "Nothing happened."

Immigration was just one of many major stories in Washington this week. There's been so much going on that we have to pick and choose what we want to talk about Sunday on "Face The Nation."

The Supreme Court handed down two landmark rulings on same-sex marriage this week, invalidating a key provision of the federal Defense of Marriage Act and clearing the way for gay weddings to resume in California. We'll sit down with former solicitor general Ted Olson, the conservative lawyer who successfully argued against Proposition 8, the California ballot measure that banned same sex-marriage in 2008. Olson once worked for Presidents Ronald Reagan and George W. Bush, but he now sides with the folks who want to strike down these laws against same-sex marriage.

We also learned overnight that James Cartwright, a former top general and personal favorite of President Barack Obama, is the target of an investigation into who leaked classified information about U.S. cyberattacks against Iranian nuclear facilities. The National Security Agency is back in the spotlight and we will talk with former NSA director Gen. Michael Hayden to break it all down on Sunday.

Finally, we'll chat with a rising star from my home state of Texas - we even share an alma mater as graduates of Texas Christian University. State Sen. Wendy Davis, who caused a stir earlier this week when she made an 11-hour filibuster against a restrictive abortion bill, will be on the show. Her stand for abortion rights stopped the bill, but Texas Gov. Rick Perry has already called another special session of the legislature to deal with the controversial measure. She'll weigh in on the upcoming fight.
