Hillary Clinton cracks Colorado pot joke

It wasn't that kind of coffee shop, but when Hillary Clinton grabbed her foamy beverage from a Colorado barista Monday, she seemed to have the state's new marijuana rules in mind.

The former secretary of state visited the Pigtrain Coffee Co. in Denver on Monday while campaigning with Democratic Sen. Mark Udall. According to the Associated Press, she admired the patterns the barista drew in the foam of their drinks -- she received a pig in honor of the coffee shop's name, while Udall got a leaf.

"Is that a marijuana plant?" Clinton laughed, alluding to the new state-sanctioned marijuana industry.

Udall is locked in a competitive race against Republican Rep. Cory Gardner that could determine which party controls the Senate next year. A Fox News poll released last week has Gardner up 6 points, 43-37 percent while a CBS News/New York Times estimate shows Udall leading by 3 points, 48-45 percent.

After her stop in Colorado, Clinton headed to Nevada, where she delivered the keynote address at a dinner for the UNLV Foundation in Las Vegas. Before giving her speech, she chatted with casino magnate Sheldon Adelson, the billionaire known for bankrolling conservative campaigns. Adelson was there to be honored for donating $7 million to the UNLV Foundation.

Clinton said that Adelson told her that he wished he could ask her questions on stage, the Las Vegas Sun reports.

"That would have been a debate," Adelson reportedly said. Recounting their friendly exchange, Clinton reportedly told people at the Bellagio, "We would have needed a boxing arena."

While on stage at the event, Clinton spoke about a range of issues including the United States' role in the world. "I don't think the United States can solve every problem in the world. But I don't think you can solve problems without the United States," she said.
