Trump’s Labor Department is using a 55-year-old presidential order spurred by the Civil Rights Movement to scrutinize companies like Microsoft and Wells Fargo over their public commitments to diversity.

But he said it’s more likely the Trump administration is using the move as a political tactic ahead of the presidential election. “It’s a chicken-and-egg problem.”The latest actions affecting contractors align with a broader Trump administration trend on matters of race.

Apple and Google's Android long ago cornered the market on phone operating systems, but Microsoft's rare partnership with Google means Duo comes with a suite of Android apps.
