From the very beginning of SESTA and FOSTA, its backers kept insisting that the bill was necessary to takedown Backpage.com. Indeed, Senator Rob Portman, in announcing SESTA, entitled his press release "Senators Introduce Bipartisan Legislation to Hold Backpage Accountable." And he's spent the past six months pointing to Backpage as the reason we absolutely needed SESTA. At launch, his quote was the following:

For too long, courts around the country have ruled that Backpage can continue to facilitate illegal sex trafficking online with no repercussions. The Communications Decency Act is a well-intentioned law, but it was never intended to help protect sex traffickers who prey on the most innocent and vulnerable among us.
