On March 1, 2018, CfA renewed its request to the Office of Congressional Ethics to investigate whether Rep. Devin Nunes (R-CA) and/or staff of the House Permanent Select Committee on Intelligence, acting at his direction violated House ethics rules by leaking confidential information, following a report in the New York Times that the committee leaked text messages between Senator Mark Warner and a Washington lawyer.

"Utah Rep. Mike Noel’s apparent failure to disclose significant land holdings worth $1.2 million near and in the Grand Staircase-Escalante National Monument has prompted a formal ethics complaint and an inquisitive letter from a Democratic congressman to the Interior Department."

On February 20, 2018, CfA called on Utah Attorney General Sean Reyes to open an investigation into Utah State Representative Michael Noel (R-Kanab) for failing to disclose conflicts of interest, making false or deceptive statements, misusing public money, and violating anti-nepotism rules.

"A national government watchdog group is calling for an investigation into Mississippian Heath Hall, the former acting administrator of the Federal Railroad Administration."

"An ethics group submitted a letter to the Department of Justice on Tuesday requesting that it launch an investigation of Heath Hall, the former deputy administrator of the Federal Railroad Administration who resigned over the weekend after allegations were raised about 'outside work' he took on while employed as a senior federal official."

On February 13, 2018, CfA asked the Public Integrity Section of the Department of Justice to investigate whether Heath Hall, former Acting Administrator of the Federal Railroad Administration, violated federal criminal law by willfully filing a public financial disclosure report in which he falsely claimed he would not be receiving outside income.

"Daniel Stevens, executive director of the Campaign for Accountability, an ethics group, said last week that Hall lacked any experience 'for the critical job of overseeing America’s rail network' and also appears to have been 'holding down a second job as a Mississippi public relations consultant in violation of federal law.'"

"Rooney told CNN the Office of Congressional Ethics has sent letters to all of the Republican committee staff of the House Intelligence Committee related to leaks. A liberal advocacy group Campaign for Accountability filed a complaint with OCE against Nunes and his staff, accusing them of leaking information related to Fusion GPS. It's not clear if the letters are tied to that complaint or if it will turn into a formal investigation, and OCE will not comment publicly on its investigations."

"The Campaign for Accountability says the leak was meant to punish the firm that produced the Trump Russian dossier."

"A government-ethics group on Thursday accused House Intelligence Committee chair Devin Nunes of improperly leaking information about the company behind the intelligence dossier concerning President Donald Trump and Russia."
