Obama's day: Congressional picnic

President Obama spends Wednesday paying tribute to his new attorney general and welcoming lawmakers to the White House for an annual tradition: The congressional picnic.

In the late morning, Obama speaks at an investiture for Attorney General Loretta Lynch, who has been on the job for nearly two months but has not had a formal welcoming ceremony.

Lynch has already made international headlines with bribery charges against World Cup soccer officials.

Education gets the spotlight in the mid-afternoon as Obama meets with the winners of the Presidential Award for Excellence in Science, Mathematics, and Engineering Mentoring.

The congressional picnic in the early evening takes place less than a week after House Democrats defeated a key part of a proposed free trade deal with Asian countries.

While Obama and free trade supporters are looking for ways to revive the free trade agreement, officials said the picnic is purely a social gathering.

"It's an opportunity for members of Congress to bring their families to enjoy a nice evening on the South Lawn of the White House," said Obama spokesman Josh Earnest. "I don't anticipate a lot of arm-twisting taking place."
