LINCOLN, Neb. (AP) — A Republican state lawmaker in Nebraska who has criticized President Donald Trump and accused the GOP of enabling racism launched a new website Tuesday to try to change the party's current views on unions, guns and climate change.

Sen. John McCollister, of Omaha, unveiled a new website dubbed “Republican Redefined."

The website lays out what McCollister describes as conservative arguments for public education, prison reform and a strong social safety net, among other issues. It also highlights Nebraska's one-house, officially nonpartisan Legislature and the senator who fought to create it.

The Nebraska Republican Party called on McCollister to leave the GOP after he tweeted in August that the GOP was “enabling white supremacy” with its support of Trump. McCollister refused, saying he's been a Republican for five decades and wants to try to reshape the party from within.

State GOP officials have argued that McCollister doesn't adhere to the party's conservative beliefs and said they were offended by his statements.
