I still remember how Google escaped antitrust enforcement during the Obama presidency. There was a "revolving door" for Google execs and White House officials who would fill positions at both places [2].
When FTC prepared a massive report of Google's antitrust violations [3], the enforcement was quashed as a result of White House lobbying by Google's lobbyists (most of whom worked for the government a year or two prior.) [4]
Lots of emails were released under FOIA showing how (former) Google execs who were at the White House told the FTC not to bring on the lawsuit. [5] [6]
