State Rep. Daryl Metcalfe is calling for Pittsburgh Mayor Bill Peduto to be impeached…after Peduto signed the controversial gun legislation into law Tuesday. Metcalfe tweeted Tuesday afternoon, saying, “I just asked our attorney to have a resolution drafted to IMPEACH the Mayor of Pittsburgh for his illegal gun control ordinances!” Peduto fired back, pointing out multiple failed bills Metcalfe has supported in the past and asking “do you really want to go 0-5?”
