"The pattern, however, has drawn attention from a watchdog group — Campaign for Accountability, whose other recent targets include payday lenders, pregnancy crisis centers, rooftop solar providers, various Republican politicians and Google. It filed one round of complaints with the FEC about Crapo's use of the townhouse, and on Thursday asked the Senate Ethics Committee to examine a disclosure issue involving the payments to Susan Crapo."

On June 21, 2018, Campaign for Accountability (CfA), a nonpartisan, nonprofit watchdog group focused on public accountability, filed a complaint with the Senate Select Committee on Ethics against U.S. Senator Mike Crapo (R-ID) for failing to disclose his wife’s income from his leadership PAC on his 2017 financial disclosure report. CfA previously filed an FEC complaint against Sen. Crapo for failing to disclose any payments for the use of a lobbyist’s Capitol Hill condo for fundraising activities.

"A self-described nonpartisan watchdog group on Thursday urged the Senate Ethics Committee to investigate possible connections between donations from the payday lending industry to Sen. Richard Shelby's campaign account and congressional votes that benefitted the industry."

"On Thursday, the watchdog group Campaign for Accountability asked two Congressional ethics committees to investigate 14 members of Congress for taking official actions in support of the payday lending industry while at the same time accepting campaign contributions from that industry."

On May 3, 2018, CfA asked the Senate Select Committee on Ethics and the Office of Congressional Ethics to investigate whether two senators and 12 representatives violated congressional rules and criminal law by accepting campaign contributions from the payday lending industry shortly before or after taking official actions in support of the industry’s priorities.

"The reimbursement came after a watchdog group filed a complaint with the FEC last week alleging that Crapo’s fundraising events constituted illegal in-kind contributions to Crapo’s campaign by the LLC that technically owns the house. Corporations are legally barred from contributing to federal political campaigns."

"On Thursday, Campaign for Accountability, a nonpartisan, nonprofit public accountability watchdog group, filed a complaint with the Federal Election Commission against Crapo and Vicki Hart, the lobbyist owner of the condominium."

"Committees for Idaho Republican Senator Mike Crapo hosted a series of campaign fundraisers at the crashpad used by Pruitt. But the committees didn’t report making any payments to the owner of the condo, according to the Campaign for Accountability, a watchdog group that has filed a complaint with the Federal Election Commission."

On April 19, 2018, CfA filed a complaint with the Federal Election Commission (FEC) against U.S. Senator Mike Crapo (R-ID) and Vicki Hart, the lobbyist owner of a Washington, D.C. condominium, for failing to disclose improper in-kind contributions, in apparent violation of the Federal Election Campaign Act (FECA) and FEC regulations.

On October 18, 2017, Campaign for Accountability filed a lawsuit in federal court in Washington DC against the Treasury Department to force the release of documents regarding Renaissance Technologies and its co-CEO, Robert Mercer.
