C4L meaning in Governmental ?

The Campaign for Liberty (C4L) is a political organization founded by twelve-term United States Congressman Ron Paul. Campaign for Liberty focuses on educating elected officials and the general public about constitutional issues, and currently provides a membership program. Its legal status is that of a 501(c)(4) nonprofit.

The Campaign for Liberty was announced on June 12, 2008, as a way of continuing the grassroots support involved in Ron Paul's 2008 presidential run, and corresponded with the suspension of that campaign. Paul formally announced during the Texas Republican Convention that he had created this new organization known as the "Campaign for Liberty".

On August 5, 2015, C4L Chairman John Tate was indicted by a federal grand jury for felony charges arising from an alleged cover-up Tate, and colleagues on the 2012 Ron Paul presidential campaign, conducted to conceal the expenditure of campaign money to buy the endorsement of an Iowa politician. In October 2015, Tate was acquitted of all charges.
