According to the Wall Street Journal, former president George W. Bush slammed the views of republican nominee Donald Trump in front of a crowd of about 400 donors at a Cincinnati fundraiser held on Tuesday.

Bush did not name Trump at the fundraiser for Sen. Rob Portman (R-Ohio), but his comments against policies of “isolationism, nativism and protectionism” were a clear jab at the GOP’s nominee platform.

Like many GOP leaders have done as a non-response to Trump, Bush has stated that he will focus his campaigning efforts on down-ballot races. Bush, as well as his father George H. W. Bush, decided to stay on the side lines this year, even though they both endorsed Mitt Romney in 2012 and John McCain in 2008. A spokesmen for the former presidents said back on May 4 that they would not participate in or comment on Trump’s presidential efforts.

The other famous Bush, former presidential candidate and FL Gov. Jeb Bush, has more solidly denounced Trump’s candidacy, and has stated that he will not voting be for him, or for Clinton, next November.

In a Facebook post, Bush accused Trump of not being a true conservative and of having no respect for the Constitution. “In November, I will not vote for Donald Trump or Hillary Clinton, but I will support principled conservatives at the state and federal levels, just as I have done my entire life,” his statement read.
