AFL-CIO President Richard Trumka said Wednesday he is crafting a new plan to remake the American labor movement, which is struggling to retain clout in Washington and state capitals amid a steep decline in membership.

In an interview taped for C-SPAN’s “Newsmakers” program, Trumka said he was seeking a more formal alliance with other key elements of the Democratic Party’s liberal base, including civil rights organizations and women’s rights groups. The hope, he said, is to then broaden union membership beyond the traditional realm of workplace-based organizing.
