"When former Texas Gov. Rick Perry took the stage to campaign for Republican Sen. Ted Cruz in Texas earlier this month, he did so walking a fine ethical line.
Perry, now head of the Energy Department, rallied a crowd Oct. 20 in Houston for Cruz by blasting Democratic Rep. Beto O'Rourke and warning that a Democratic win could wind back the clock on burgeoning exports of domestic liquefied natural gas — a hot selling point in energy-rich Texas.
DOE said Perry's spirited appearance was off the clock and in his personal capacity. And the Republican didn't use his formal title of DOE secretary during the event."
