Donald Trump will endorse Rep. Paul Ryan at a rally in Green Bay, Wisconsin tonight, Fox News reported. Trump has hinted that he might not endorse Ryan, after Ryan was slow to back Trump's presidential bid. Earlier this week, Trump said he was “not quite there yet” on endorsing Ryan in his House race against far-right challenger Paul Nehlen. Nehlen, who said this week that he supports deporting all Muslims, has enjoyed the backing of conservative media figures like Ann Coulter and Sarah Palin, the same cohort that supports Trump’s campaign. More mainstream Republicans, including Trump's own running mate Mike Pence, have endorsed Ryan, pressuring Trump to pick a side.
