Next Tuesday, I’m trying something new. Catch my "twitterview" with Sen. John McCain, R-Ariz., on Tuesday, March 17 at 12 noon ET on Twitter. We’re going to attempt to conduct a full interview exclusively on Twitter — complete with the 140-character limit! All a part of exploring new ways to connect with our "This Week" viewers online. This week I "tweeted" with Sen. Claire McCaskill, D-Mo., about her vote against the omnibus legislation on Twitter. And I’ve been enjoying replying to viewers’ questions online. So, if you have any suggested questions for me to ask Sen. McCain — in 140 characters or less — "twitter" me! Hope you’ll join us. –George Stephanopoulos Follow ABC News’ Chief Washington Correspondent and "This Week" host George Stephanopoulos on Twitter HERE, and Sen.
