JUDY WOODRUFF:

Now to the 2016 presidential campaign.

The vast amount of attention in this election year, by far, has gone to the two main party nominees for president, Hillary Clinton and Donald Trump. But there are a few third-party candidates competing as well.

Tonight, we hear from the woman who is the nominee of the Green Party for the second election in a row. She is Dr. Jill Stein, and I spoke with her a short time ago.

Dr. Jill Stein, welcome to the "NewsHour."
