However, the second tweet, from the president's personal account, was not visible on Saturday to all of his 68 million followers.
"By making public the unsubstantiated name of the whistleblower Trump encapsulated the pathology of his presidency", wrote Aaron David Miller, senior fellow at the Carnegie Endowment and former State Department analyst.
Democrats, some Republicans, and members of the US intelligence community have strongly objected to the effort to reveal the whistleblower's identify, calling it inappropriate and possibly illegal. That person first alerted members of Congress to Trump's conduct in his July 25 phone call with Ukrainian President Volodymyr Zelenskiy in a nine-page memorandum.
She also said that in addition to focusing on Trump's "abuse of power", lawmakers should "be focusing on the subpoenas that have already been issued for Don McGahn and for Mick Mulvaney, who have firsthand knowledge of what the president did".
But Van Hollen, who heads the Democratic Congressional Campaign Committee, warned that any Senate trial that barred both sides from calling witnesses or providing new documents would amount to a "sham" and a "rigged trial".
In August, the whistleblower filed a report expressing concern over a phone call on July 25 in which Trump asked his Ukrainian counterpart Volodymyr Zelensky to investigate Joe Biden, former Vice President and a Democratic front-runner for the 2020 U.S. presidential election.
"No responsible government official or lawyer in the USA could credibly argue that someone who brings a complaint to the inspector general is not protected by the statute", Colapinto said.
Trump insists he did nothing wrong in his dealings with Ukraine and has asserted that the whistleblower made up the complaint, despite its corroboration by other officials.
The Democratic delay of the impeachment process holds many political gifts for Trump and his party.
Late on Friday, Trump shared a post from Twitter user @surfermom77 which names the alleged whistleblower.
Mr Biden is now the leading Democrat candidate in the party's primaries.
That photo was removed Saturday and replaced with an image of Trump. That tweet also was removed and the original account had been suspended as of Saturday.
"That's not something most humans are doing", Hauser stated.
Facebook has a policy banning posts that name the alleged whistleblower.
Some particulars concerning the whistleblower which have been revealed on-line by Trump's supporters have been inaccurate or misrepresented.
Michael German, an Federal Bureau of Investigation whistleblower who left the company after reporting allegations of mismanagement in counterterrorism circumstances, stated outing authorities whistleblowers not exclusively places them at private threat but additionally discourages different authorities officers from stepping ahead to reveal potential wrongdoing.
"(Biden) is closer to the centre of the electorate than his major rivals Warren, Sanders, Mayor Pete and maybe Mike, and he is closer to the centre of the Democratic electorate", said Paul Beck, a professor of politics at Ohio State University in Columbus.
