You're throwing yourself on the mercy of Associated Press.

You haven't committed plagiarism, because the article was properly credited. You have committed copyright infringement, unless you have explicit permission from AP to reproduce the article in its entirety here. The two are separate offenses. If they notice, they are within their rights to sue you. They will win.

The guidelines for fair use include reproducing no more than 10% of a work, or in the case of artwork, not what is considered "the heart" of the work, without permission. Fair use governs reproduction for the purposes of instruction, criticism, and news reporting (which is where you are).

For your own protection, I suggest you alter your practice to quoting of a couple of interesting sentences, with citation and a link to the complete article. In that case, even if the webpage you cite has improperly reproduced the article and is in violation of the Copyright Act, you aren't.
