(AP) — An audit says U.S. Sen. Josh Hawley used a state vehicle to travel to political events during his time as Missouri attorney general.

State Auditor Nicole Galloway released the audit Thursday.

Her office found that Hawley has reimbursed some expenses after making campaign-related stops while using a state vehicle but he owes more.

The audit also found that there is an appearance of impropriety but no evidence that laws were broken in work that Hawley’s campaign consultants did with attorney general staffers.

Hawley says he’s pleased with the audit results but says there was bias in the Democratic auditor’s review.

“Now that all of the facts are available, it is clear that this report is based solely on evidence provided by current and former Attorney General’s Office staff and political consultants who worked with the office. There was no bias.”

But the partisan manipulation & potential unethical practices Galloway’s office engaged in during audit raise major questions that need to be addressed in future. People of Missouri deserve answers. Auditor is supposed to be independent & nonpartisan. This one isn’t #mogov #moleg
