Speaker of the House Nancy Pelosi, D-California, announced Tuesday that the House of Representatives is moving forward with an official impeachment inquiry against President Donald Trump.

Pelosi said in a news conference Tuesday afternoon that Trump’s actions represented a "betrayal of his oath of office, a betrayal of our national security and betrayal of the integrity of our elections."

A whistleblower complaint about a phone call Trump made to a world leader and mounting pressure from more progressive members of her party has led Pelosi to make the announcement, according to The Washington Post.

On Tuesday, Trump said he has authorized the release of the full transcript of a phone call he had with Ukrainian President Volodymyr Zelensky in which some have reported that he brought up investigating former Vice President Joe Biden and his son.

Pelosi has said in the past few months that neither the Republicans in the Senate nor the American public has much of a stomach for impeaching proceedings.

However, Pelosi said on Tuesday that Trump’s phone call to Zelensky is an offensive that is “most understandable” to the public, and may have pushed the House leader toward launching impeachment hearings.

To impeach a president, 218 members of the House of Representatives must vote in favor of the articles of impeachment. There are 235 Democrats in the House.

If the House approves the resolution, the process moves to the Senate where a trial is then held.

It takes a two-third majority vote for a president to be convicted of the charges brought in the article of impeachment. There are 48 Democrats in the Senate.

Here is a list of House Democrats who have indicated they would support articles of impeachment as of 5 a.m.ET Friday.
