Hide your tweens, because the awesomely virginal threesome known as the Jonas Brothers will be hitting up our nation’s capital today.  Well, at least Joe Jonas will be. The middlest of the JoBros is coming to DC to support and advocate the proposed Eunice Kennedy Shriver Act of 2010. This Act is named after the late Eunice Kennedy Shriver, who dedicated much of her life to the philanthropic endeavors of the Special Olympics. Joe Jonas will be teamed with Timothy Shriver and Anthony Shriver, who works for Best Buddies International, to support this worthy cause.
