A new bipartisan bill known as the Honest Ads Act is the first major attempt to regulate online platforms that sell ads with rules akin to those that apply to more traditional advertising on TV, radio and in print.

The bill, introduced today by Democratic Senators Mark Warner and Amy Klobuchar with a bipartisan boost from Republican Senator John McCain, imposes regulations on social platforms, websites, ad networks and other online entities with more than 50 million unique users per month.
