"Earlier today I had an unfortunate confrontation with a Capitol Hill Police Officer. It is traditional protocol that Capitol Hill Police Officers secure 535 Members of Congress, including 100 Senators. It is the expectation of most Members of Congress that Capitol Hill Police officers know who they are. I was urgently trying to get to an important meeting on time to fulfill my obligations to my constituents. Unfortunately, the Police Officer did not recognize me as a Member of Congress and a confrontation ensued. I did not have on my Congressional pin but showed the Police Officer my Congressional ID.
"I know that Capitol Hill Police are securing our safety, that of thousands of others, and I appreciate the work that they do. I deeply regret that the incident occurred. I have demonstrated my support for them in the past and I continue to support them now."

Showed her ID before, or after she slapped/punched him? So, it took less time to punch the guy than it would have to just wear the pin so he could easily identify her? That makes sense. I still don't see where she regrets hitting him.
