Only Sixteen Democrats in U.S. House Aren’t Co-Sponsoring Bill for D.C. Statehood

Only sixteen Democrats in the U.S. House are not co-sponsoring HR 51, the bill to make almost all of the District of Columbia a state. By state, they are:
Arizona: Tom O’Halleran
California: Nancy Pelosi
Indiana: Pete Visclosky
Maine: Jared Golden
Michigan: Elissa Slotkin
Minnesota: Collin Peterson
New Jersey: Jeff Van Drew
New Mexico: Xochitl Torres Small
New York: Anthony Brindisi, Joseph Morelle
Oklahoma: Kendra Horn
Pennsylvania: Conor Lamb
South Carolina: Joe Cunningham
Tennessee: Jim Cooper
Utah: Ben McAdams
Wisconsin: Ron Kind

The bill has no Republican co-sponsors. Even the Republican Delegates from American Samoa and Puerto Rico have not co-sponsored it. UPDATE: this post originally listed 17 Democrats, but on October 30, Arizona Congressmember Greg Stanton co-sponsored the bill, so the post has been amended.
