Timeline: Special counsel's probe into Trump's efforts to overturn 2020 election

Here's a look at how special counsel Jack Smith's investigation into former President Donald Trump's efforts to overturn the 2020 election results has unfolded.

Former acting U.S. attorney Jack Smith was appointed in November to oversee the investigation into efforts by former President Donald Trump and his allies to overturn the results of the 2020 election.

Here is how the special counsel probe has unfolded.

Attorney General Merrick Garland appoints Jack Smith as special counsel to oversee the entirety of the Justice Department's criminal investigation into the efforts to overturn the 2020 election, as well as the unlawful retention of national defense information at former President Donald Trump's Mar-a-Lago estate. The announcement is triggered when Trump's announcement that he is running for president for a third time creates a potential conflict of interest with the Justice Department.

Smith previously served as the chief prosecutor for the special court in The Hague charged with investigating war crimes in Kosovo.

Smith issues subpoenas to officials from multiple states that were targeted by Trump and his allies in the failed attempt to reverse his loss to Joe Biden.
