Rep. #Steve Scalise was among those who were shot at a GOP practice at Simpson Field in #Alexandria on Wednesday morning. Governor Doug Ducey: "Thoughts and prayers for @ SteveScalise + all affected in senseless event this morning".
U.S. Capitol Police Chief Matthew R. Verderosa said his officers who were wounded "are in good condition" and should recover quickly. After medical personnel arrived, he said he retrieved Scalise's phone and made the first call to Scalise's wife to notify her of the shooting. Everyone on that field is a public servant - our courageous police, our congressional aides who work so tirelessly behind the scenes with enormous devotion, and our dedicated members of Congress who represent our people.
