Trump shared a tweet stating the name of the person who allegedly denounced him, leading to an investigation into the dismissal of the president.

The tweet tweeted by President Donald Trump's Twitter account on the evening of December 27 stems from an account called "Surfermom77". This person describes himself as "100% supportive of Trump." The tweet mentioned "whistleblower" accused him of pressuring Ukraine and claimed that he had made a false statement.

By December 28, the tweet no longer appeared on Trump's Twitter account timeline, but it was still visible to certain users and accessible via a direct link. In the evening, Twitter acknowledged that a technical error occurred causing some people to see the tweet tweet again, but others did not.

For months, Trump has threatened to reveal the identity of the accuser, complaining that he has the right to face the person who reported him. On the evening of December 26, he also posted on Twitter a link to a Washington Examiner article that mentioned the whistleblower's name. The name of the alleged alleged Trump also appeared in several other conservative media, including Breitbart News. The White House has yet to comment.

Under US law, the identity of a whistleblower must be kept confidential to keep them safe.

The US House of Representatives opened an investigation to oust Trump in September after accepting a charge from an anonymous person. The House Intelligence Committee released a 300-page impeachment investigation report on December 3, saying evidence of Trump's misconduct and congressional Congress was "very strong".

Trump will only be deposed if two-thirds of the senators vote against him, but this is unlikely because the Republican party controls the Senate. There are two US presidents who have been impeached before Trump. President Bill Clinton was impeached in 1998 for a scandal with the White House intern at Monica Lewinsky but was acquitted in the Senate. President Andrew Johnson was impeached in 1868 but was not convicted in the Senate.
