Denver City Council is attempting to close a loophole allowing campaign spending to go unreported if not coordinated directly with a candidate’s campaign.

The measure would adopt the state definitions of independent expenditure and electioneering communication. It would also require individuals or entities making independent expenditures to file a report within two days of spending more than $1,000, itemize all contributions received exceeding $25, and clearly identify the source of funding for any paid advertising.

If the bill passes, other changes to city campaign finance laws would include differentiation between issue committees and other political committees, as well as a requirement for quarterly reports in the calendar year before an election and additional reporting in the weeks leading up to an election.

Council has scheduled a final vote for Sept. 11.
