He confirmed that an email he had written to the campaign after that trip to Moscow was presented to him during Thursday’s appearance before the House Intelligence Committee.
Mr. Page acknowledged his meeting with Russian government officials during sharp questioning by Representative Adam B. Schiff of California, the top Democrat on the committee, according to a congressional official familiar with the exchange.
During another part of the testimony, Mr. Page was questioned about a trip to Budapest, although it was not immediately clear why. Mr. Page told The Times earlier this year that he had taken that trip around Labor Day weekend last year, but he said he had not met with any Russians.
“It was a short four-day trip over a long holiday weekend at the end of the summer,” Mr. Page said at the time. “I had a nice trip up the Danube, to the Visegrad castle, did a lot of sightseeing and went to a jazz club. Not much to report.”
Court records unsealed on Monday revealed that another campaign adviser, George Papadopoulos, met in 2016 with Russians who said they had connections to the government and was told about “dirt” regarding Hillary Clinton in the form of “thousands of emails.” The court records were released by Robert S. Mueller III, the special counsel investigating Russian attempts to disrupt the presidential election last year and whether any of President Trump’s associates helped in that effort.
Mr. Page was questioned by the F.B.I. earlier this year and has also appeared before the grand jury as part of the special counsel’s inquiry.
The House Intelligence Committee is one of three congressional investigations that are also examining these issues.
