Donald Trump’s presidential campaign faced scrutiny over its poll performance, internal management and foreign policy as the Republican nominee intensified his attacks on the news media.

Trump accused the press of protecting Democratic rival Hillary Clinton, misrepresenting his words and failing to show the size and enthusiasm of his rally crowds. He claimed he would be leading Clinton by 20 percentage points if coverage were honest. He singled out The New York Times for a report citing anonymous colleagues who described him as exhausted and frustrated, calling its account fiction. At a Connecticut rally, he also suggested he might revoke the paper’s reporters’ credentials. An opinion passage agreed that much of the media wanted Trump to lose but said Republican nominees had faced similar treatment before.

Trump’s campaign chairman, Paul Manafort, blamed news organizations for concentrating on controversial remarks instead of Trump’s economic plan. Those remarks included Trump’s suggestion that Second Amendment supporters could “do something” if Clinton appointed liberal judges and his repeated, false assertion that President Barack Obama founded the Islamic State group.

Trump was preparing an Ohio speech in which aides said he would propose ending nation building and adopting a foreign policy focused on defeating the Islamic State group and other terrorist organizations. He was expected to call for cooperation with countries sharing that goal, suspend visas where adequate screening could not be performed and introduce an ideological test for admission. Running mate Mike Pence said Trump would provide specifics on counterterrorism and defended him against criticism from Republican national security experts.

Meanwhile, Vice President Joe Biden planned to campaign with Clinton in Scranton, Pennsylvania, where he was expected to call Trump unprepared on national security and praise Clinton’s proposals for jobs and education. Clinton’s campaign also launched a voter registration effort aimed at mobilizing Latino voters through young undocumented immigrants protected by an Obama administration program. Although those immigrants cannot vote, the campaign hoped they could encourage eligible relatives and others to register.

Separately, a New York Times investigation drew attention to Manafort’s work for a pro-Russia Ukrainian political party and his connections to a network Ukrainian investigators said had been used to loot assets and influence elections. Former Trump campaign manager Corey Lewandowski, who had clashed with Manafort before being fired, shared the article on Twitter, prompting speculation about tensions between the two men.
