Director of National Intelligence Dan Coats repeatedly found his warnings about the threat posed by Russia suppressed by the White House, The New York Times reported in the wake of his resignation from the post.

According to the Times, Coats has often found himself at odds with President Trump over Russia, a situation which worsened in recent months.

Coats saw Russia as an adversary to the US, the Times wrote, and pushed for closer cooperation with European countries to counter it, but the White House did not agree. 

Several times Coats saw his language on the Kremlin's activities watered down by the White House, according to the Times.

A secret report by Coats on Russia's attempt to interfere in the 2018 mid-terms by spreading disinformation was reportedly altered by the White House. A public statement on Coat's conclusions contained less critical language than the original, the Times said. 

A former senior intelligence official told the Washington Post that Coats felt marginalized on national security issues by the president, and had come to see his departure as inevitable.

According to reports, Trump had been discussing replacing Coats for months.

Trump has long faced scrutiny for his warm comments on Russia, and his changing positions on whether Russia interfered to help him secure his 2016 election victory.

Former special counsel Rober Mueller found that there was insufficient evidence to charge the president and his aides with deliberately conspiring with Russia in 2016.

Trump in a tweet Sunday announced that Coats would step down in mid-August, and nominated Texas Rep. John Ratcliffe as his replacement. 

In his tweet, he thanked Coats for his service but offered him no praise. 

"The intelligence community is stronger than ever and increasingly well prepared to meet new challenges and opportunities," wrote Coats in his resignation letter, citing the recent appointment of an official charged with countering foreign election interference.

During his time as national security director, Coats had publicly contradicted Trump on his claims regarding Russia and North Korea. 

In a statement released after Trump's controversial summit in Helsinki with Russian president Vladimir Putin in July 2018, Coats rebutted the president's apparent acceptance of Putin's claim that Russia had not interfered in the 2016 election. 

At a national security conference in Colorado last year, Coats reacted with incredulity when told that Trump had invited Putin to the White House at the summit. 

"That's going to be special," he remarked.

And in testimony before the Senate Intelligence Committee in January, Coats contradicted Trump's claims that North Korea no longer posed a threat because of his summits with its leader, Kim Jong Un.

Coats told lawmakers that North Korea "was unlikely to give up" its nuclear weapons. He also contradicted Trump's claim that Iran was seeking to gear up its nuclear program. 

In contrast to Coats, Rep. Ratcliffe is a Trump loyalist who has backed Trump's claims that Mueller 's probe into Russian interference was a partisan plot to unseat Trump.

In an interview with Fox News on Sunday, he said: "the Mueller report and its conclusions weren't from Robert Mueller. They were written by what a lot of people believe was Hillary Clinton's de facto legal team."
