Donald Trump, the 45th President of the United States, has been the subject of various investigations during and after his time in office. Some of these investigations were related to his business dealings, while others were related to his political campaign and allegations of misconduct while in office.
One investigation that received significant attention was the investigation led by Special Counsel Robert Mueller into Russian interference in the 2016 U.S. presidential election and possible collusion with the Trump campaign. This investigation did not find evidence of criminal collusion, but it did document numerous instances of Russian interference in the election and identified a number of individuals associated with the Trump campaign who had contacts with Russian officials.
Another investigation that received significant attention was an impeachment inquiry launched by the U.S. House of Representatives in 2019, following allegations that President Trump had pressured the President of Ukraine to investigate a political rival. The House subsequently voted to impeach President Trump on charges of abuse of power and obstruction of Congress, but the Senate voted to acquit him of those charges.
There have also been investigations into President Trump's business dealings, including allegations of tax fraud and violation of campaign finance laws. These investigations have resulted in a number of legal proceedings, including criminal charges and civil lawsuits.
