(CNN) Some of special counsel Robert Mueller's investigators have told associates that Attorney General William Barr did not properly convey how damaging their findings were for President Donald Trump, The New York Times and The Washington Post reported.

The investigators said Barr, in his memo to Congress, did not adequately portray the results of their nearly two-year investigation into Russian interference in the 2016 election, the Times reported Wednesday, according to government officials and others familiar with their frustrations. Investigators have concerns that Barr was able to shape the public's initial views of their report with his memo and now, without the report being made public, they are set in that narrative, according to the Times.

Those interviewed by the Times declined to fully explain why the Mueller investigators believe their findings were more damaging to Trump than Barr disclosed.

Members of the special counsel's team also complained to close associates that the evidence they compiled on whether Trump obstructed justice was "alarming and significant," the Post reported Thursday.

Some of Mueller's investigators were also caught off guard by Trump's victory lap after the Barr letter was released, people familiar with their response told the Post.
