Billionaire Charles Koch and his network of political donors will not be supporting Republican nominee Donald Trump, instead re-directing their focus to supporting Republicans in competitive Senate races. Mr. Koch has raised concerns about Trump's stance on the free market. He and his network, which includes influential billionaires and millionaires, has evolved from a small group to a powerful political force with 1,600 staffers spread across 38 states. "At this point I can’t support either candidate, but I’m certainly not going to support Hillary," Koch said. The Koch network, which has invested hundreds of millions of dollars into politics, planned on pouring a lot of money into the 2016 presidential race. Instead, they will be investing in competitive Senate races, including in Ohio, Pennsylvania, and Florida.
