Mayor Nutter will be in Washington D.C. Wednesday to testify before a Congressional panel on gun violence.

No word yet on whether he will drop any expletives on Capitol Hill, as he has in other settings when he discusses this issue. He will appear at a 2 p.m. hearing convened by U.S. Rep. Nancy Pelosi titled, "Gun Violence Prevention: A Call to Action."

Others testifying include Scott Knight, Chief of Police, Chaska, Minn., and former chair of the International Association of Chiefs of Police Firearms Committee; Emily Nottingham, mother of Gabe Zimmerman, the community outreach director for Rep. Gabrielle Giffords, who died in the Tucson, Az., attack; and Janet Robinson, superintendent of schools, Newtown, Conn.
