Facebook will give Congress Russian-bought ads on Monday

On Monday, Congressional investigators will receive Facebook ads bought during the 2016 presidential campaign by Russian operatives, the company says. Lawmakers will get roughly 3,000 ads purchased by a Russian troll farm that focused, in part, on divisive political issues. The company is also providing data on how the ads were paid for and targeted to users on Facebook.

The bigger picture: Facebook initially said it wouldn't hand over the ads, but it's under intense political pressure to provide as much information as possible as part of the probe into Russian election interference. Twitter also briefed investigators last week and is facing similar pressure. Lawmakers could choose to make details about the ads public.
