Investigation
In America’s 243-year history, only three previous presidents have faced impeachment proceedings. The Constitution does not prescribe a specific process and neither does federal law, leaving Congress to set its own rules. Here’s how the fourth impeachment unfolded over more than four months.
SEPT. 24, 2019
Initiation
Speaker Nancy Pelosi announced a formal
impeachment inquiry, directing a handful of
House committees to continue their monthslong
investigations into President Trump.
Closed-door testimony
Congress was handed important findings from multiple investigative efforts, including from special prosecutors, for the impeachment inquiries of Presidents Richard M. Nixon and Bill Clinton. Kenneth Starr investigated Clinton, and Archibald Cox pursued Nixon. In this impeachment, House committees are doing that job.
Adam B.
Schiff
Carolyn B.
Maloney
Eliot L.
Engel
The committee leaders for the House Intelligence,
Oversight and Reform, and Foreign Affairs
Committees have been issuing subpoenas, taking
depositions and conducting closed-door meetings.
Financial
Services
Ways and
Means
Two more committees, Ways and Means and
Financial Services, also have ongoing
investigations into issues related to Mr. Trump.
OCT. 31
House vote on impeachment rules
In October 1998, the House voted 258 to 176, with 31 Democrats breaking ranks with the president, to begin a full-scale, open-ended inquiry into possible grounds for the impeachment of Clinton.
The House voted to approve a resolution that laid out the rules for the impeachment inquiry into Mr. Trump.

In 1998, four hearings were held in connection with Clinton’s impeachment by the Judiciary Committee. The hearings lasted for two days.
Jerrold Nadler, Chairman
After receiving the report, the Judiciary Committee held two more
hearings. The first hearing invited legal scholars to discuss whether Mr.
Trump’s conduct amounted to an impeachable offense. In the second
hearing, staff lawyers from the Intelligence Committee presented their
dueling reports on the investigation. The president and his counsel were
invited but declined to participate.

The House Judiciary Committee’s Democratic majority
released two proposed articles of impeachment against
Mr. Trump, charging the president with abuse of power
and obstruction of Congress.

delivered the articles of impeachment to the Senate,
which served as the jury.
