A number of his associates who spoke to The New York Times have painted Trump as being exhausted, bewildered, sullen and erratic. Trump has blasted the article, calling the Times a “failing newspaper of fiction”—although Trump has reportedly not asked for any retractions. A recent Reuters poll shows nearly one-fifth of registered Republicans want Trump to drop out of the race. In public, however, the Republican Party is continuing attempts to project unity. On Friday, Republican National Committee Chair Reince Priebus made a surprise appearance at a Trump rally in Erie, Pennsylvania, where he introduced and hugged Trump. At this rally, Trump attempted to walk back his recent comments calling President Obama the founder of ISIS. Instead, Trump said his comments had been sarcastic—”but not that sarcastic.” This comes as Trump is slated to release his proposals for fighting ISIS during a speech in Ohio today. He’s also expected to further explain his plans to significantly limit immigration, which at times have included calls for a complete ban on all Muslims. His campaign is now also suggesting a test intended to vet immigrants’ views on issues, such as women’s and gay rights.
