altSen. Barbara Mikulski (D-Md.) reassured Secretary of State Hillary Clinton on Monday that it was okay she was photographed drinking beer in Colombia earlier this month.

"It's not always safe to drink the water but the beer is pasteurized," Mikulski noted.

Mikulski also referred to President Obama's speech at the White House Correspondents' Association dinner on Saturday, when he said Clinton "won't stop drunk-texting me from Cartagena."

"Despite what the president said you were doing in Colombia, I know you were at your duty station," she said.

Clinton and Mikulski were speaking at Fortune magazine's "Most Powerful Women" reception at the State Department Monday evening.

The secretary of state also had warm words for Mikulski, noting she was the longest serving woman in Congress and added that "when I was in the Senate we called her the dean."

Clinton had to excuse herself from the dinner following the reception, noting she was headed to the National Geographic building to host a dinner for the prime minister of Japan and then had to fly to China.

Monday night's dinner was the first in the magazine's "Most Powerful Women Evening With..." series, which will take place in several cities across the country to celebrate women leaders. 

At the event, held in the Benjamin Franklin Room at the State Department, Fortune editor Nina Easton spoke with Google vice president Susan Molinari, former White House communications director Anita Dunn, and Obama adviser Samantha Power about women's roles in Washington.
