In recent weeks, Pelosi accused the president of engaging in "a cover-up", characterized his actions as "villainous to the constitution" and made a joking reference to the 25th amendment - which allows a president to be removed from office if he is deemed unfit to serve.
The speaker, according to Politico, made the remark while defending her stance against impeaching the president in an evening meeting with House Judiciary Committee Chairman Jerry Nadler and other top Democrats.
Democratic strategist Jon Summers countered by saying Special Counsel Robert Mueller did not pursue a case on obstruction of justice only because he knew Justice Department guidelines prohibited him from indicting a sitting president.
I've been around the people of our area for more than 50 years - much of that time in public life.
Trump continued: "But Nancy Pelosi-I call her Nervous Nancy-Nancy Pelosi doesn't talk about it. Nancy Pelosi's a disaster, OK, she's a disaster and let her do what she wants".
Democrats have called on Mueller to testify before Congress.
President Donald Trump and First Lady Melania Trump attend a French-US ceremony at the Normandy American Cemetery and Memorial in Colleville-sur-Mer, Normandy, northwestern France, on June 6, 2019, as part of D-Day commemorations marking the 75th anniversary of the World War II Allied landings in Normandy. The team found that some Russians did interfere in the election but stated that they could not establish conspiracy or cooperation between Trump's team and Russian actors. "Charging the president with a crime is not an option we could consider".
Mueller said during the public appearance on May 29 that his team was limited by Department of Justice policy and could not charge the president with a crime.

He stressed that many conflicts in the world could be resolved only by combined efforts of the United States and Europe. Pompeo said he hoped that Germany would "follow Britain's example" and ban Hezbollah.
In addition to Nadler, who has been battling behind the scenes to control any impeachment investigation, the other Democrat House committee chairs were present at the meeting.
Nadler thinks impeachment is not supported by the people because they don't know the facts.
The entrenched anti-Trump media became hysterical for what they saw as the final straw that would convince Speaker Nancy Pelosi to cave in to the extreme left in her party and get underway with Trump's prosecution.
A Pelosi spokesperson told the New York Post the lawmakers "had a productive meeting about the state of play with the Mueller report".
"When that decision has to be made, it will be made not by any one individual - it will be made probably by the caucus as a whole", Nadler told CNN.
This has put pressure on Pelosi, whether she is willing to admit it or not.
She has also sought to project unity within her Democratic Party on the path forward regarding impeachment. "Certainly Nancy will have the largest single voice in it".
