A state audit of History Colorado questioned the use of employee credit cards meant for official functions.
The audit released Tuesday found that History Colorado spent about $1 million for expenses classified as official functions from 2009 through 2014. But auditors noted that many of the official-function purchases were for individual coffees or lunches.
History Colorado maintains museums and historical sites around the state. The agency also preserves and exhibits collections of historical significance. Most of the group's funding comes from state cash funds.
History Colorado officials say they're working to implement controls on employee credit-card use.
The audit also found that grant funding for historic preservation projects has dropped dramatically since 2003, mostly due to legislation that has diverted money for other things, including restoration of the state Capitol dome.
