Donald Trump’s 2016 presidential campaign faced scrutiny over its direction, the candidate’s recent remarks and his advisers’ ties to Ukraine, while both Trump and Hillary Clinton prepared to sharpen their messages on national security and immigration.

Trump blamed his falling poll numbers on what he called dishonest and corrupt media coverage, claiming he would lead Clinton by 20 percentage points if the press treated him fairly. He rejected a New York Times account that cited anonymous colleagues describing him as exhausted and frustrated, and accused the newspaper of inventing sources. He also complained that coverage failed to show the size and enthusiasm of his rally crowds and suggested revoking Times reporters’ credentials. His campaign had previously denied credentials to several other news organizations.

Campaign chairman Paul Manafort likewise blamed the press for emphasizing Trump’s controversial comments over his economic plan. Those comments included a remark 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. One editorial excerpt agreed that much of the media wanted Trump to lose, while observing that Republican nominees before him had faced similar opposition.

Trump was expected to outline his foreign policy in an Ohio speech, proposing an end to nation building and a focus on defeating the Islamic State and other terrorist groups. His aides said he would call for cooperation with countries sharing that goal. He was also expected to propose halting visas where adequate screening could not be performed and introducing an ideological test for admission, including questions about religious freedom. Running mate Mike Pence promised specifics and defended Trump against criticism from Republican national security experts.

Clinton, meanwhile, prepared to campaign in Scranton, Pennsylvania, with Vice President Joe Biden. Biden planned to portray Trump as uninformed and unprepared on national security while praising Clinton’s proposals for jobs and education. Her campaign also launched a voter-registration effort involving young undocumented immigrants, known as DREAMERs, who cannot vote but can mobilize eligible voters. The effort sought to reach Latino voters and highlight the risk Trump posed to protections established under Obama.

Separately, a New York Times investigation reported new details about Manafort’s work for Ukraine’s pro-Russia political party and his connections to a network that 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, drew attention by tweeting a link to the report.
