Donald Trump intensified his criticism of the news media as reports of campaign turmoil and a drop in polling put pressure on his presidential bid. In a series of tweets, the Republican nominee called the media “disgusting” and accused it of protecting Hillary Clinton, misrepresenting his words and failing to convey the size and enthusiasm of his rally crowds. He claimed that fair coverage would put him 20 percentage points ahead of Clinton.

Trump singled out The New York Times over an article citing anonymous colleagues who described him as exhausted and frustrated. He called the reporting fiction and, at a rally in Connecticut, suggested he might revoke the newspaper’s press credentials. An opinion passage argued that media hostility toward Republican nominees was not unique to Trump, citing previous Republican presidents. Campaign chairman Paul Manafort also blamed the press for a difficult week, saying it had emphasized controversial remarks over Trump’s economic proposals. Those remarks included a comment about what Second Amendment supporters could “do something” about if Clinton appointed liberal judges, and his repeated false assertion that President Barack Obama founded the Islamic State group.

Trump’s aides said he would use an upcoming speech in Ohio to outline a foreign policy centered on defeating the Islamic State and other terrorist organizations, while ending nation building. They said he would advocate working with countries that shared that goal, even where disagreements remained. He was also expected to propose withholding visas when adequate screening could not be performed and introducing an ideological test addressing issues such as religious freedom. Running mate Mike Pence promised more specifics on security and defended Trump against criticism from Republican national security experts.

Clinton planned to campaign with Vice President Joe Biden in Scranton, Pennsylvania. Biden’s office said he would portray Trump as unprepared for the presidency and a danger to national security, while praising Clinton’s proposals for jobs and education. Her campaign also launched a voter registration effort tied to the anniversary of Obama’s program protecting some young undocumented immigrants brought to the United States as children. Although those immigrants cannot vote, the campaign hoped they would help mobilize eligible Latino voters.

Separately, a New York Times investigation brought renewed scrutiny to Manafort’s work for a pro-Russia political party in Ukraine and his ties to a network Ukrainian investigators said was used to loot assets and influence elections. Former Trump campaign manager Corey Lewandowski, who had been fired after clashing with Manafort, drew attention by sharing the article on Twitter soon after its publication.
