HELSINKI, Finland — President Trump on Sunday spent the eve of his first summit meeting with President Vladimir V. Putin of Russia finding fault with allies, Barack Obama and the news media while refraining from condemning Moscow for its meddling in the 2016 presidential election.
His comments raised the stakes for the meeting, a closely scrutinized encounter that the White House said would include a 90-minute session in which the two presidents will speak one-on-one, with only their interpreters present.
