WASHINGTON — The Republican-led House intelligence committee on Friday released a lengthy report concluding it found no evidence that Donald Trump’s campaign colluded with Russia in the 2016 presidential campaign, a finding that drew praise from the president and rebuttals from Democrats.

The House panel did find that Russia sought to sow discord in the U.S. through cyberattacks and social media.

The report caps an investigation that began with the promise of bipartisanship but quickly transformed into an acrimonious battle between Democrats and Republicans over Russia’s meddling in the 2016 election and whether there were any connections with the Trump campaign.

Trump quickly claimed vindication on Twitter Friday morning, writing, “Just Out: House Intelligence Committee Report released. ‘No evidence’ that the Trump Campaign ‘colluded, coordinated or conspired with Russia.’ Clinton Campaign paid for Opposition Research obtained from Russia- Wow! A total Witch Hunt! MUST END NOW!”

But the committee’s Republicans didn’t let the Trump campaign completely off the hook. They specifically cited the Trump campaign for “poor judgment” in taking a June 2016 meeting in Trump Tower with Russian operatives and dubbed the campaign’s praise of WikiLeaks “objectionable.”

“While the committee found no evidence that the Trump campaign colluded, coordinated, or conspired with the Russian government, the investigation did find poor judgment and ill-considered actions by the Trump and Clinton campaigns,” the House Intelligence Committee wrote.

The report’s conclusion is fiercely opposed by committee Democrats, who accused their Republican colleagues of playing “defense counsel” for the White House throughout the investigation.

“Committee Republicans chose not to seriously investigate — or even see, when in plain sight — evidence of collusion between the Trump campaign and Russia,” said Rep. Adam Schiff of California, the top Democrat on the probe, in a statement. Schiff cited several “secret meetings and communication” between people linked to Russia and Trump campaign officials including former National Security Adviser Michael Flynn and the president’s eldest son, Donald Trump Jr.

Schiff called on the committee to publicly release the transcripts from dozens of interview with key witnesses, saying the public should be able to judge the evidence gathered by the committee. Rep. Mike Conaway, R-Texas, meanwhile called on intelligence officials to clear the committee to release more information from the report that was deemed classified. The 253-page document is packed with details and assessments, but is also spackled with redacted names and blacked-out passages. Democrats also released a 98-page rebuttal .

The House investigation is the first of several inquiries probing Russian election interference to conclude. An investigation led by special counsel Robert Mueller is ongoing, as are probes led by the Senate intelligence and judiciary committees.

In a statement, Conaway said he was “extremely disappointed with the overzealous redactions” made by the intelligence agencies. He said many of the blacked out details include information already public such as witness names and previously declassified information.

Conaway said the committee had pledged to be “as transparent as possible” with the report.

“I don’t believe the information we’re releasing today meets that standard, which is why my team and I will continue to challenge the IC’s many unnecessary redactions with the hopes of releasing more of the report in the coming months,” he said.

House investigators cautioned that Russia will continue meddling in U.S. elections and suggested some fixes that would help the government and politicians better defend against that interference.

The panel wrote that intelligence officials should immediately alert presidential candidates when they discovers “legitimate” threats to the campaign and also tell Congress. The panel also recommended the executive branch “crack down” on leaks by conducting polygraphs of all for limited certain employees with top secret clearances.
