Lamar Companies is a national billboard and real estate firm whose political giving skews toward Republicans and corporate Democrats. Its president and CEO, Mark Kalkus, is a Trump donor, and under his leadership the company has funneled money into GOP committees and moderate Democrats who protect business interests. While Lamar markets itself as a neutral advertising company, its leadership’s political ties place it firmly within the conservative donor network that bankrolls anti-regulation and pro-developer policies.
