I’m not convinced it is a good thing that both are being investigated if the investigation into Buttigieg is just political smearing. HRC’s emails show the cost of abusive investigations. Investigations aren’t cost free, either monetarily or in terms of public trust in institutions. It implies he did something worth investigating, and devalues the seriousness of real investigations, like those against Trump.
When the review was announced, Buttigieg had flown on FAA planes 18 times out of 138 flights for official trips since becoming secretary early in 2021, according to The Washington Post. He takes commercial flights most of the time, and when he uses FAA aircraft, it’s usually because it’s cheaper than commercial flights, a Department of Transportation spokeswoman said.
This does not seem to be something worth investigating.
