Law enforcement officials accused a 26-year-old man from a town west of Boston of plotting to blow up the Pentagon and the Capitol Building with a remote-controlled aircraft fitted with explosives. Officials said Rezwan Ferdaus, who has a physics degree from Northeastern University, has also provided resources to Al Qaida to aid in attacks on American soldiers overseas.

"Question 1" on Tuesday's ballots in Maine, much like last year's "Proposition 8" in California, would explicitly revoke recently granted marriage rights for gay and lesbian couples in Maine if it passes. The initiative asks:

"Do you want to reject the new law that lets same-sex couples marry and allows individuals and religious groups to refuse to perform these marriages?"

Abby Goodnough, from The New York Times, gives us an overview of the initiative and its national significance. We're also joined by Shenna Bellows, from Maine's ACLU; and Brian Souchet, from the anti-gay-marriage group Stand for Marriage Maine.

An alleged terror plot in Boston is again raising questions about just how big the actual threat of homegrown terrorism is. Tarek Mehanna, 27, has been charged with plotting to "kill, kidnap, maim or injure" people in the United States. Prosecutors say Mehanna and others discussed attacking a shopping mall and two U.S. politicians. Explaining the case against Mehanna are Abby Goodnough, Boston Bureau Chief for The New York Times, and Richard Falkenrath, deputy commissioner of counterterrorism for the New York Police Department.
