AP story on filibuster wrong

The story says:

While it takes only a majority vote to change Senate rules, it takes 60 senators to end a filibuster.

No! No! No!  It takes 67 votes to change a Senate rule.  More on the flip.

From the Senate rule XXII:

"Is it the sense of the Senate that the debate shall be brought to a close?" And if that question shall be decided in the affirmative by three-fifths of the Senators duly chosen and sworn -- except on a measure or motion to amend the Senate rules, in which case the necessary affirmative vote shall be two-thirds of the Senators present and voting -- then said measure, motion, or other matter pending before the Senate, or the unfinished business, shall be the unfinished business to the exclusion of all other business until disposed of.

What the Republicans are talking about doing is ignoring the written laws of the Senate and using their majority to vote down any challenges to their actions.  How can a report get such a simple point wrong?  Any suggestions on how to get AP to correct their story?
