The non-partisan National Taxpayers Union (NTU) endorsed the 72 Online concept.

NTU endorsed following standard statement:
"We support the 72 Online rule to require generally that legislation and conference reports be posted on the Internet for 72 hours before floor consideration in Congress."

Note: Endorsers of the 72 Online concept do not necessarily support or oppose any legislation, nor agree with the views of ReadtheBill.org or other endorsers on specific legislation or other matters.

"Legislators should at least have the courtesy to read their own bills before foisting them onto taxpayers as laws. Congress has relied on its own version of "stealth" tactics to evade basic budget principles and pass some of the most egregious earmarks. The 72 Online rule would provide citizen groups like NTU more time to thoroughly check the fiscal radar and detect these threats. This will greatly benefit the American taxpayer."

--Kristina Rasmussen, Sr. Government Affairs Manager, National Taxpayers Union

NTU was established in 1969 to educate taxpayers, the media, and elected officials on a non-partisan basis on the merits of limited government and low taxes.

This good piece from 2004 is worth a read. Balko praises the Washington Post op-ed by Rep. Brian Baird on this subject.

This great piece from a libertarian perspective connects Hayek's "Iron Law of Oligarchy" with the need for a legislative cooling off period. It's definitely worth reading the whole thing.
