Washington (CNN) The National Rifle Association previously agreed to pay $6.5 million to buy a mansion for CEO Wayne LaPierre, The Wall Street Journal reported Tuesday.

A top NRA executive, then-Chief Financial Officer and Treasurer Wilson H. Phillips Jr., signed a document in May 2018 promising the gun lobby would contribute $6.5 million for 99% ownership of a company formed to buy a Dallas mansion for LaPierre, according to a copy of the document reviewed by the Journal. The NRA and its then-outside advertising firm, Ackerman McQueen, told the Journal that the planning to buy the home started in the wake of the Parkland, Florida, mass shooting, when LaPierre had concerns about his safety. The deal ultimately fell through.

The report comes as the NRA faces intense scrutiny of its finances, internal turmoil and leadership changes. New York Attorney General Letitia James in April launched an inquiry into the organization , which is chartered in New York. A gun-control group has also filed a complaint with the IRS , challenging the NRA's tax-exempt status.

Earlier this year, the NRA ousted its president, Oliver North, following a dispute with LaPierre in which North accused him of financial misconduct, according to the Journal.

NRA spokesman Andrew Arulanandam told the Journal: "As we have said repeatedly, neither Mr. LaPierre nor the Board ever formally considered, much less approved, an investment in the house in question or the other properties shown by Ackerman McQueen's real estate agent."
