The Seattle City Council unanimously passed two bills banning most political spending by foreign-influenced corporations and clamping down on political advertising.

These bills are part of the Clean Campaigns Act, a three-bill package introduced in August of last year.

The first bill prevents corporations with a single foreign national investor holding at least 1% ownership, or two or more holding at least 5% ownership from contributing directly to Seattle candidates, political races, or through PACs.

Companies that have a non-U.S. investor making decisions on its U.S. political activities will also be prevented from political spending.

The measure closes a loophole because foreign individuals and foreign-based entities already are barred from making contributions in U.S. elections.

The second bill adds transparency to the political advertising realm.

It requires any paid advertisement regarding a political matter of local importance to follow stricter reporting guidelines and to retain and provide records about these advertisements.

The third bill, which would place a cap on Super PAC contributions, remains in the Select Committee on Campaign Finance Reform for further discussions.
