A dozen different Gülen groups have sponsored congressional travel since 2008 and have filed forms with the House certifying that they were paying for the trips. The House Ethics Committee approved all the trips in advance based on the forms the Gülen groups submitted.
But a USA TODAY investigation found many of those disclosures were apparently false. Some of the Gülenist groups claimed to be certified nonprofits, but they do not appear in state or IRS databases of approved charities. Groups that did register with the IRS filed tax forms indicating that they did not pay for congressional travel. And five of the groups admitted to congressional investigators earlier this year that a Gülenist group in Turkey was secretly covering the costs of travel inside Turkey for lawmakers and staff.
