The committee Republicans said they agreed that Russia sought to influence the election by spreading propaganda and false news reports via social media. However, they disputed the findings of the Central Intelligence Agency, National Security Agency and Federal Bureau of Investigation that Moscow sought to aid Trump, who won a surprise victory over Democrat Hillary Clinton.
Representative Adam Schiff, the top committee Democrat, strongly disagreed, and blasted the announcement as a premature shutdown.
The House investigation, one of three main congressional probes of Russia and the 2016 investigation, and possible collusion or obstruction of justice by Trump or his aides, has been marred for months by partisan wrangling, including the release of rival Republican and Democratic memos related to the probe.
The House Intelligence Committee's chairman, Republican Representative Devin Nunes, recused himself from the investigation last year amid reports he had a secret meeting at the White House. Nunes denied wrongdoing.
The House Republicans made their announcement even as Robert Mueller, the U.S. special counsel for the Russia probe, seems to be stepping up his investigation. Last week, former Trump campaign aide Sam Nunberg spent six hours before a grand jury called by Mueller, and former Trump campaign manager Paul Manafort pleaded not guilty to criminal charges.
"While the Majority members of our committee have indicated for some time that they have been under great pressure to end the investigation, it is nonetheless another tragic milestone for this Congress, and represents yet another capitulation to the executive branch," Schiff said in a statement.
Conaway rejected that charge.
