Here's a look at some of the day's top stories from WTOP:
New Jersey Gov. Chris Christie is proving again he doesn't mind a little humiliation: The Republican on Tuesday posted on his Facebook page a video showing two of his kids dumping a bucket of ice water on his head.
The video is part of the Ice Bucket Challenge, launched by the ALS Foundation to raise money for fighting ALS, also known as Lou Gehrig's disease. Christie nominates three other people to complete the challenge within 24 hours or donate $100: Democratic New Jersey U.S. Sen. Cory Booker, Facebook founder Mark Zuckerberg and late-night TV host Jimmy Fallon.
The ALS Foundation reports raising $4 million since July 29 thanks to the Ice Bucket Challenge.
Another 130 U.S. troops have arrived in Iraq on what the Pentagon describes as a temporary mission to assess the scope of the humanitarian crisis facing thousands of displaced Iraqi civilians threatened by militants from the group Islamic State.
Defense Secretary Chuck Hagel says, ``This is not a combat boots on the ground kind of operation.''
Instead, Hagel calls the 130 troops ``assessors.''

A federal judge has ruled a Maryland ban on 45 assault weapons and a limit on gun magazines to 10 rounds is constitutional. U.S. District Judge Catherine Blake released the ruling on Tuesday in Baltimore.
Maryland lawmakers approved the sweeping gun-control law last year in response to the December 2012 shootings at Sandy Hook Elementary School in Newtown, Connecticut. Attorneys who argued against key provisions in the law contended it violated Second Amendment rights. But lawyers for the state countered that the state took a reasonable approach by focusing on firearms used in military-assault style attacks and mass shootings to protect the public.
