Toronto Mayor Rob Ford says he doesn't smoke crack cocaine and isn't an addict, in response to a video that surfaced recently purporting to show him using the illegal drug.

Last week Ford called the cellphone video obtained by The Toronto Star "ridiculous" and blamed the newspaper for "going after me."

Friday's comments from Ford were more emphatic.

It's difficult for an American president to govern through nuance, especially when it's necessary to persuade a majority of the people that certain actions are essential for national security. And effective persuasion usually requires clarity.

That's how you arrive at President George W. Bush's stark formulation "You're either with us, or you're with the terrorists" after Sept. 11, and much of what sprang from it.

In the days since a tornado ripped through Moore, Okla., talk of constructing safe rooms in public schools has become commonplace.

Billionaire Paul Tudor Jones is back-peddling from remarks he made at a symposium last month that motherhood causes women to lose the necessary focus to be successful traders.

But as the U.S. apparel industry continues to shrink, LA's bluejeans business faces a threat: a nearly 40 percent tariff, imposed by the European Union, that could cripple the city's jean business.

When people talk about Ilse Metchek they use phrases like "she's a piece of work," "a force of nature," "she's something else." If you want to talk fashion, she's your lady.

They were just little girls when they were killed in 1963, in what came to be known as the 16th Street Baptist Church Bombing. And now Addie Mae Collins, Denise McNair, Carole Robertson, and Cynthia Wesley have been awarded the Congressional Gold Medal, nearly 50 years after the attack in Birmingham, Ala.

President Obama signed the legislation Friday to award the girls — all of them 14, except for McNair, who was 11 — with the highest honor Congress can bestow upon a civilian.

There are two things you can always count on: public radio pledge drives and the local blood bank asking for a donation of a very different sort.

Both kinds of giving can fill you with a sense of goodwill. But, let's be honest, the tote bags help, too.
