Teddy Schleifer for CNN:

Stephen Adams, a billboard magnate who made his fortune in a half-dozen different business ventures over the last five decades, is pouring hundreds of thousands of dollars into a pro-Trump campaign. Yet it is not the Trump campaign or a Trump super PAC that is spending over $650,000 to boost the Republican nominee — it is Adams himself, who his buying his own billboards in a set of swing states.

It is an unusual purchase and a throwback to a previous era when the wealthy had close to unfettered control over how their dollars were spent. Adams disclosed the spending this week in independent expenditure reports almost always filed by political action committees or nonprofits, rather than individuals: $150,000 in North Carolina, $200,000 in Pennsylvania and $300,000 in Michigan.
