For obvious reasons, Facebook’s looking to up political advertising transparency ahead of the midterms. Back in May, the social network introduced Ad Archive, a searchable database of political ads in the U.S. It’s following up the feature with a new Ad Archive Report, a weekly snapshot of political spending.

The survey offerings a breakdown of top spenders by campaign, including the amount spent and the number of ads run. The first report for ads on Facebook and Instagram from between May and October 20, shows a total of $256 million spent across 1.6 million ads.
