What are the chances that Donald Trump faces an impeachment trial within his first 100 days in office?

I'd say very low. Due to the sweeping changes in congress, I'd say opposition to Trump would be hard pressed to get the needed 2/3 majority congress requires to apply that official censure. Many people think that impeachment removes the president from office. It does not, it can build pressure for that to happen, but like with President Clinton, a President can be impeached and still remain in office.

None whatsoever.

Zero

Many are screaming words like illegal, unconstitutional or beyond the scope of the office but provide no proof of evidence to validate their assertions. The impeachment process would take much more then the first hundred days to complete. But first and foremost you need to provide solid evidence not conjecture because you have different opinions and ideas then the other person. Although many within the Republican Party do not care for POTUS they will not turn on him. In the United States, impeachment at the Federal level is reserved for those who may have committed "high crimes and misdemeanors". The federal procedure in the United States involves a vote for impeachment in the House of Representatives on a document known as the Article of Impeachment. Each separate grounds will be a separate Article. House members who support the impeachment then appoint managers who will act like prosecutors in the preparation for the Senate hearing. The hearing for removal is conducted in the Senate and in the case of the impeachment of a President, the Chief Justice of the Supreme Court of the United States presides over the proceedings (otherwise the Vice-president presides) which are conducted as a trial with witnesses being heard under oath or affirmation. The defendant has the right to legal counsel, the right to cross-examine all witnesses and to testify in his defense. The senators must also take an oath or affirmation that they will perform their duties honestly and with due diligence. The Hearing cannot be conducted without a 50% plus one quorum. After the Hearing the deliberations are held in private. Removal requires a two-thirds majority of the Senate.

I am truly curious just what one thinks he has done that would even qualify for impeachment.

I heard a few cries for Obama to be impeached early in his tenure also. He too did nothing of an impeachable nature.

Just for thought. Not being liked is not grounds for impeachment.

Zero.

Slim to none.
