With just three weeks before the election, this has been a week of controversy on the campaign trail.

With one month left in the 2016 election, a 10-year-old tape of a "hot mic" conversation with Donald Trump was released showing lewd comments about women.

"It's a rare opportunity to see a contrast between the two candidates on any issue."

First Lady Michelle Obama campaigned for Hillary Clinton in battleground Virginia on Friday, proving to be an effective surrogate for her husband's former secretary of state.

Trump once again stole the campaign spotlight as he flew to Mexico for a meeting with President Enrique Peña Nieto hours before delivering a hard-line immigration speech.

Clinton spent much of the week off the campaign trail raising money for a record-setting August.
