How Donald Trump Could Be Impeached
The impeachment process was established in order to remove a president from office if he or she is found guilty of a crime committed against the United States. Almost certainly the president will never be prosecuted under the law, and will only be asked to leave office. There have only been two presidents impeached while in office: Andrew Johnson and most popularly, Bill Clinton. As stated previously, both presidents saw no punishment post-presidency.
The most popular way a president can run into legal issues would be obstruction of justice. Failing to provide info or blocking means of information in order to "save face" could prove enough for the Congress to warrant an impeachment. The impeachment process is heard by the Senate and called for by the House. During the hearing, a select group of members from the House of Representatives serve as a jury of some sort. The most formal impeachment process would involve the prosecution of a president, however it has never come to such major circumstance. Typically, if a president understands they have a good chance of being impeached, they will step down and hand the job over to the vice president, in order to save themselves from years of scrutiny and embarrassment. This was most namely seen in the case of Richard Nixon following the "Watergate" scandal.
The impeachment process is one of the ways presidents are held in check throughout their time in office.
How Trump Might Face Impeachment
Recent developments have arisen following Trump's firing of FBI Director Comey. Some speculate Donald Trump fired Comey before he was able to testify against Trump for using Russia as a way to win the 2016 presidential election. It has long been analyzed whether Russia did or did not in fact play a role in the election, however Russia themselves have said they meddled. Whether this is true or not has still gone unproven.
The fact that the meddling has not been proven is one reason why it will be so hard to impeach Trump. If Russia can not even be proved to have messed with the election, Trump may make the argument there was nothing for him to cover up, and blame the Comey firing on the media being too involved with the mess that he had to fire him just to get them to stop talking about the issues.
Also, Donald Trump currently enjoys a majority in both the House and Senate, proving why it may be hard for him to even be tried in the first place.
While the media may act like Trump is likely to face impeachment, the real probability is highly unlikely.
