When Donald Trump won the presidency, many Republicans were relieved after eight years of Democratic rule. During the first year of his presidency, though, Trump has charted a new path for the GOP – one that has some conservatives questioning the future of their party.

Kirk’s Frontline documentary “Trump’s Takeover” airs tonight at 9 on PBS stations.
