CCUL's Bob Arnould said only $135,000 of that total came from the league, with $75,000 coming from the San Manuel tribe. The remaining balance remains in the PAC coffers, he said.

Miller disagreed with Arnould's $135,000 figure, saying the league was lying about the donations, and challenged Arnould to “look at the check” written to Aguilar. Restoring Our Community is the league's PAC, and the league's name is on the check.

The CCUL did cut a check for $250,000, but it was the seed money Ramos-Ingold referred to that funded the PAC, not a direct payout to Aguilar, according to the FEC.

Miller said he was visited Thursday by “five or six” credit unions as part of the NAFCU Caucus' advocacy activities. The credit unions were “very apologetic” about the donation to Aguilar, and some said they would take up the issue with the league, Miller said.

FEC documents show the California League's regular PAC contributed the maximum $5,000 on April 23 to Aguilar. Four large credit unions in the region also contributed to Aguilar's campaign: Wescom CU, SchoolsFirst FCU, Kinecta FCU and California Coast CU.

Miller received a $5,000 contribution from CUNA's PAC in 2010 and $1,000 in 2011, but no donations are on record with the FEC for 2012. NAFCU's PAC donated $2,500 to Miller in 2012. Arnould said the CCUL donated to Miller's campaign recently, as he advances to the general election, but the FEC does not have record of it at this time.
