Carmel, Indiana—Republican presidential hopeful Donald Trump speaks during a campaign stop on May 2. Now that he’s the presumptive nominee, some Republicans have cautioned the real estate developer to tone down his rhetoric heading into the July convention. Speaker Paul Ryan urged Trump to get in line on key GOP political and ideological issues such as trade, the military, abortion and immigration, saying he was “not ready” to endorse Trump otherwise. Trump brushed off Ryan and said he would not rule out blocking the speaker from serving as convention chairman.
