This does not sound good. From Roll Call:

Police labor union officials asked acting Chief Christopher McGaffin this afternoon to allow a Capitol Police officer to complete his investigation into an early-morning car crash involving Rep. Patrick Kennedy (D-R.I.).

According to a letter sent by Officer Greg Baird, acting chairman of the USCP FOP, the wreck took place at approximately 2:45 a.m. Thursday when Kennedy’s car, operating with its running lights turned off, narrowly missed colliding with a Capitol Police cruiser and smashed into a security barricade at First and C streets Southeast.
…
“The driver exited the vehicle and he was observed to be staggering,” Baird’s letter states. Officers approached the driver, who “declared to them he was a Congressman and was late to a vote. The House had adjourned nearly three hours before this incident. It was Congressman Patrick J. Kennedy from Rhode Island.”

Baird wrote that Capitol Police Patrol Division units, who are trained in driving under the influence cases, were not allowed to perform basic field sobriety tests on the Congressman. Instead, two sergeants, who also responded to the accident, proceeded to confer with the Capitol Police watch commander on duty and then “ordered all of the Patrol Division Units to leave the scene and that they were taking over.”

Kennedy did recently get into an accident in Rhode Island. Maybe he just can’t drive. As they say in the business, this story is unfolding…
