Prometheus 6

Via Pandagon I see this:

His name is Steve Gardner. He's also known as "The 10th Brother," as in Band of Brothers. He's one of two members of Sen. John Kerry's 12 Vietnam swift boat crew members who refused to stand with Kerry at the Democratic Convention. The other man remained silent.

"They said I had a political agenda. I had no and have no political agenda whatsoever. I saw John Kerry on television saying he was running for the Democratic nomination for president, and I knew I couldn't ever see him as commander in chief -- not after what I saw in Vietnam, not after the lies I heard him tell about what he says he did and what he says others did."

OooooKAY!

What does "political" mean? What does "agenda" mean? And in what language?
