Donald Trump intensified his attacks on the news media as his presidential campaign faced falling poll numbers and reports of internal dysfunction. In a series of tweets, the Republican nominee accused journalists of protecting Hillary Clinton, misrepresenting his statements and failing to show the size and enthusiasm of his rally crowds. He claimed that honest coverage would put him 20 percentage points ahead of Clinton.

Trump focused particular criticism on The New York Times after it quoted unnamed colleagues describing him as exhausted and frustrated. He called the account fiction and suggested at a Connecticut rally that he might revoke the newspaper’s press credentials. His campaign chairman, Paul Manafort, also blamed news organizations for concentrating on controversial remarks rather than 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 claim that President Barack Obama founded the Islamic State group. An opinion passage acknowledged that much of the media opposed Trump but argued that Republican nominees had faced similar hostility before.

Trump planned to address foreign policy in Ohio, where aides said he would call for ending nation building and pursuing “foreign policy realism” focused on defeating the Islamic State and other terrorist groups. He was expected to propose working with countries that shared that goal, suspending visas where adequate screening was impossible and introducing an ideological test for admission. Running mate Mike Pence said Trump would offer specifics on national security and defended his criticism of Obama’s record.

Clinton’s campaign, meanwhile, launched a voter-registration effort aimed at mobilizing eligible Latino voters through young undocumented immigrants known as DREAMERs. The campaign said it would highlight the threat a Trump presidency posed to Obama’s program protecting some immigrants brought to the United States as children. Vice President Joe Biden also planned to campaign with Clinton in Scranton, Pennsylvania, arguing that Trump was unprepared on national security and that Clinton would support working families.

Separately, a New York Times investigation drew attention to Manafort’s consulting work for a pro-Russian Ukrainian political party and his ties 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 story on Twitter, prompting comments about tensions between the two men.
