(CHICAGO) Another leading Illinois Republican is refusing to endorse Donald Trump for President.

West Suburban conservative Congressman Peter Roskam tells “The Big John Howell Show” on WLS, that he has problems with some of Trump’s positions.

“You know he thinks taxes are gonna end up going up, I don’t know a lot of Republicans that want to start at a tax hike.

Or that the entitlement programs are all fine. I think most folks realize they’re not fine.

Roskam was asked what it would take for him to come around to endorsing the presumptive Republican nominee for President.

“I haven’t yet. I’m in that category where I want to see him move but you know it’s also this notion of Hillary Clinton, oh my goodness!”

Roskam said he could never support Clinton for President, calling her a “miserable alternative.”

Roskam’s fellow conservative Congressman Randy Hultgren has also said he is not ready to endorse Trump.

Moderate Republican Adam Kinzinger says he may never be able to endorse him, and another moderate Republican, Bob Dold, has flat out said that not only will he not endorse Trump, he will not even be voting for him.

Dold is locked in a tight re-election battle in his North Shore district that includes many liberals and moderates.

Republican Governor Bruce Rauner has said he will not endorse Trump but Rauner has not said if he will vote for him. Republican U.S. Senator Mark Kirk has said he would endorse Trump.
