Have you tried the Member and Committee rosters in CapitolTrack? Click MEMBERS / CMTES to the right of Workspace and try out the four types of rosters. Find member, committee, member staff and even committee staff contact information:
Sort the Rosters by clicking on a column header or drag a header to the bar above the table to group by that selection. In this example I’ve grouped the Member Roster by both House and Party. When you have the contact information you’re looking for you can export the roster to Excel!
