"I was sad to see it go," former Sen. Fred Thompson, better known outside political circles as the series' "D.A. Arthur Branch," said in an interview set to air Wednesday on CNN's John King, USA.
Adding that the popular crime series "meant a lot to me personally," Thompson joked with CNN Chief National Correspondent John King that the television drama took him from the "obscurity of the United States Senate" and elevated him to being New York City's fictional district attorney.
"At least we'll have reruns probably for more than the rest of our lives," the attorney-turned actor-turned lawmaker told King.
The former lawmaker, who returned to politics for a 2008 White House bid, also weighed in on the current political climate and November's midterm elections.
"I'm happy not to be on the ballot in any year," said Thompson. "I think this year more than others."
Of the current climate, where voters are turning out to be especially leery of incumbents and candidates identified with Washington's political establishment, Thompson added, "When I step back and look at it from a little bit of distance, I see two things.
"I see guys who have been around for a long, long time. And I see a country that's in a process of bankrupting itself if we don't do better. You put those two things together and people are just trying to be heard."
And, echoing recent comments from Mississippi Gov. Haley Barbour, Thompson told King that he believes the current environment is more favorable to the GOP than in 1994, when Republicans took control of the House and Senate in that year's midterm elections.
"Here, I think that the concern has made itself known a lot further in advance, with a lot more intensity than in 1994. I'd be surprised if it wasn't bigger than 1994. Whether or not that translates into taking either house or anything like that, I don't know," Thompson said.
Finally, Thompson explained his use of sarcasm-laced tweets to criticize the way the Obama administration is battling terrorism.
"I think they would be much better served if they spent more time trying to come up with effective anti-terrorist policies than they did on their political correctness doctrine," the conservative Republican said.
"I mean, the very notion of not being able to identify our enemy or refusing to do so - every time we have a terrorist attempt or a terrorist attack, the initial reaction is to jump to a conclusion other than the possibility of a terrorist attack or something that's coordinated.
"All those are troubling indicators. I think the least it deserves is a little humor poked their way as we try to remind them that we're in a serious problem here and on the front end of it. We're going to have to be tough and we're going to have to be serious and frank with the American people if we're going to keep a handle on it."
