I’m re-reading Craig Whitlock’s April 2013 Washington Post article on Niger and the US military in Africa:

Human-rights groups have also accused the U.S. government of holding its tongue about political repression in Ethiopia, another key security partner in East Africa.

“The countries that cooperate with us get at least a free pass,” acknowledged a senior U.S. official who specializes in Africa but spoke on condition of anonymity to avoid retribution. “Whereas other countries that don’t cooperate, we ream them as best we can.”

The official said the administration of former president George W. Bush took the same approach in Africa. Many U.S. diplomats and human-rights groups had hoped Obama would shift his emphasis in Africa from security to democracy, but that has not happened, the official added.

“There’s pretty much been no change at all,” the official said. “In the end, it was an almost seamless transition from Bush to Obama.”
