PHOENIX - The House Ethics Committee is expanding its investigation into potential violations by Arizona Congressman David Schweikert.
The committee established a probe in June to determine whether Schweikert and/or his former chief of staff Oliver Schwab misused office funds and received improper campaign contributions.
The investigation found additional potential improprieties that the committee unanimously voted to examine.
Schwab resigned in July after seven years as Schweikert's chief of staff.
The subcommittee voted Thursday to expand its review to determine whether Schweikert violated the House Code of Official Conduct or any other law, rule or regulation.
Schweikert's office told The Arizona Republic that they look forward to providing any information necessary to the committee to resolve the matter.
