The House Judiciary Committee launched an investigation today (March 4) into the “alleged obstruction of justice, public corruption, and other abuses of power by President Trump, his associates, and members of his Administration”

The committee, chaired by New York Democrat Jerrold Nadler, is ultimately responsible for passing any articles of impeachment against a president, and this investigation starts a process that could possibly result in proceedings to remove Trump.

As a first step, the committee sent document requests to 81 different individuals and organizations, from Trump’s first White House press secretary, Sean Spicer, to supporters such as the National Rifle Association, in “order to begin building the public record.”

The requests include asking David Pecker, CEO of American Media Inc., which publishes the National Enquirer, to turn over all the information he has on the “purchase of rights for any narrative, personal account, documentation, recording, or photograph” related to Donald Trump, and any documents Trump’s sons Eric and Don Jr. may have related to dozens of meetings and situations.

The list doesn’t include the president’s daughter Ivanka, who Trump’s former lawyer Michael Cohen testified was closely involved in plans to build a Trump Tower in Moscow while Trump was running for president. However, the list of 81 is just the beginning, Nadler’s office said today.

Here is a look at all 81 people, companies, agencies, legal entities and organizations:
