On Thursday, Capitol Police rushed to respond to an emergency where a 34-year-old woman tried to drive her car through Capitol barriers. She was shot dead by Capitol Police after they tried multiple times to stop her car. One Capitol Police officer was injured.

Lawmakers are still at an impasse on how to pass a continuing resolution (CR) to fund the government, which has been shutdown since midnight Tuesday. House Republicans have tried to use the funding measure to defund and repeal parts of ObamaCare, but Senate Democrats have said the House needs to pass a “clean” CR without any riders.

During the shutdown, Capitol Police are not paid, yet they’re expected to work — they receive back pay once the government reopens. 

Most senators have been sporting a button Friday that is supposed to show appreciation for the law enforcement officers. Heitkamp said lawmakers should be doing more to make sure those who are assigned to protect them are receiving paychecks.

“It’s not enough to wear a button,” Heitkamp said. “We have got to start solving the impasse.”

It's unclear where the fight will go from here, with both sides digging in for the first government shutdown since 1996.
