Facebook last week said it would support efforts to regulate political ads. Now US senators are urging Alphabet and Twitter to do the same.

The Honest Ads Act is a senate bill that would require tech companies to disclose how political ads were targeted and how much they cost. It's sponsored by Sen. Amy Klobuchar, a Democrat from Minnesota, and Sen. Mark Warner, a Democrat from Virginia. The act was drafted in response to Russian trolls abusing Facebook and other online platforms to sow discord among Americans during the 2016 US presidential election.
