PHOENIX (3TV/CBS 5) -- Arizona Congressman David Schweikert could soon be hit with a subpoena after refusing to cooperate with an ongoing ethics investigation into his office.
The Office of Congressional Ethics this week released a 242-page report recommending Schweikert, along with current and former staff members who also declined to speak to investigators, be subpoenaed.

The report mostly focuses on Schweikert’ s former chief of staff, Oliver Schwab, who is accused of inappropriately spending public funds.
The report also recommends that the House Ethics Committee continue to investigate the allegations against Schwab.
Schweikert said in a phone interview that many of the allegations of wrongdoing were made by a disgruntled former member of his staff.
