Earlier this month, Donald Trump became the third President to be impeached by the House of Representatives. It's been a bitter partisan battle ever since the Democrats launched their inquiry this past fall.

But if you think things are bad now, wait until you hear the story of Andrew Johnson, who was the first president to be impeached.

Historian David O. Stewart recently joined Fox News Rundown host Dave Anthony to explain why our 17th president was almost thrown out of office and why times were more turbulent then they are now.

The author of "Impeached: The Trial of Andrew Johnson and the Fight for Lincoln's Legacy" explains what events led up to America's first impeachment, the nasty partisans battles that took place and why Johnson was eventually acquitted.

The original segment only told part of the story of what happened in 1868. Because the conversation was so long, we could only include some of the stories and information David O. Stewart shared with us.

On the Fox News Rundown you'll hear our full conversation with Stewart and how the Senate trial was run over 150 years ago and how that chapter in American history compares to today.
