“The political network backed by billionaires Charles and David Koch is planning to step up its advertising to unseat Democratic Senators Claire McCaskill of Missouri and Joe Donnelly of Indiana, who are seen as vulnerable because they’re from states President Trump won in 2016,” Bloomberg reports.
“The Koch-affiliated group Americans for Prosperity says it will run almost $4 million in television and online ads targeted at the two lawmakers. The spending follows a similar $4 million ad buy announced by the group in February targeting them.”
