Now some fresh pickings from the Political Grapevine:

True or False

Some people are taking on President Obama for what they say are inaccuracies in his criticism of Arizona's immigration law. Here's what he said at a Cinco de Mayo event Wednesday: "We can't start singling out people because of who they look like, or how they talk, or how they dress."

But critics say the Arizona law doesn't allow that. It stipulates questioning can come only after a lawful stop, detention, or arrest. Lawmakers specifically amended the measure last week to address complaints about possible profiling. One of the changes strengthens restrictions against using race or ethnicity as the basis for questioning. Another clarified that officers are not required to question victims or witnesses about their legal status.

Despite these changes, a senior administration official tells Fox:"The amendments do not eliminate the administration's strong concerns about this law."

Flag Flap

Tensions are running high in a California school district where administrators sent five students home Wednesday for wearing American flag t-shirts on Cinco de Mayo.

Extra police have been brought in to respond to any problems at Live Oak High School in Morgan Hill. Local media reports quote the teens as saying they were told their clothing was "incendiary" and could trigger fights. Hundreds of other students were wearing red, white and green clothing for the Mexican holiday.

The school district issued a statement Thursday saying the boys should not have been disciplined for wearing patriotic clothing.

At least 100 Latino students walked out of class Thursday and marched to city hall to protest the boys' shirts.

Sagging Standards

And from shirts to pants, specifically saggy jeans in the news after a British teenager won the legal right to wear them.

18-year-old Ellis Drummond faced an anti-social behavior order that included a ban on "wearing trousers so low beneath the waistline that members of the public are able to see his underwear."

But the ban was withdrawn after a district judge ruled some of the requirements could violate the boy's human rights. We heard a member of the EU Parliament fighting for vacation as a human right. Now this judge in England says saggy jeans are a human right as well.
