Margaret Peterlin is leaving her AT&T senior VP-global external & public affairs at the end of the year, according to Politico.
She took the AT&T job in July 2008 after serving as chief of staff to former Secretary of State Rex Tillerson.
Peterlin joined AT&T as it dealt with the fallout connected to paying Michael Cohen, President Trump's former fixer, a $600K consulting fee.
AT&T CEO Randall Stephenson later admitted the outlay paid to get a better handle on the president's thought process was a "big mistake."
Prior to signing on at Tillerson's team, Peterlin was a communications officer in the US Navy, national security advisor to ex-House Majority Leader Dick Armey and former Speaker Dennis Hasert.
Peterlin has agreed to stay on for two months at AT&T to advise Jim Cicconi, who recently returned to its DC office as senior executive VP.
In an internal announcement, Cicconi credits Peterlin with strengthening A&T's relationships with third-party groups both overseas and in the US.
