Also, POLITICO's Mike Allen "Turns the Table" on David and asks him about the debt ceiling debate and this week's Twitter Town Hall. Watch here. 

U.S. Treasury Secretary Tim Geithner

• Geithner is the last senior member of Pres. Obama's original economic team. The Chicago Tribune writes that despite handling huge crises and intense criticisms, he "has prevailed to win a reputation as a steady hand amid turbulent times."
• In this profile for The Atlantic,Joshua Green writes, "Geithner will be recognized as Barack Obama’s key lieutenant in the struggle to right the economy and fix the finance system."
• Rumors are swirling that Geithner will leave his post after a deal is struck to raise the debt ceiling. Bloomberg reports, though, that Geithner told President Bill Clinton, his work is "the only thing I’ve ever done. I believe in it. We have a lot of challenges as a country. I’m going to be doing it for the foreseeable future.”
• Watch Geithner's last appearance on MTP in April of this year. He was already talking about the debt ceiling and the President’s plan to balance the budget.

Meet the Candidate: Tim Pawlenty

• In a speech Pawlenty's campaign staffed called "a major economic policy address," Pawlenty promised high growth, low taxes and tight spending. The New York Times analyzed his promises and the quick Democratic response to his claims.
• The New York Times says Pawlenty's announcement speech pointed to one way he'd try to distinguish himself from other candidates: "He made repeated references to honesty and truth, a word that he used 16 times during the course of a 20-minute speech."
• This 2002 profile from Minnesota Public Radio looks at Pawlenty when he was a gubernatorial candidate in Minnesota and getting flack from critics who said "Pawlenty's pragmatism has tarnished his ideological purity."

In the midst of a very busy day, the NBC News political unit joined David Gregory to break down the Anthony Weiner resignation, Medicare, and the latest 2012 news from the NBC News/Wall Street Journal poll.

Deputy Political Director Mark Murray analyzed the good news and bad news for the president from our latest poll.  The positive forPresident Barack Obama is his 49 percent approval rating – six points ahead  of Mitt Romney.  The bad news is that the poll shows undecided voters tend to be much more pessimistic about the current state of the economy.

“You can see the potential that if things don’t get better, that this could be a trap for the president,” Murray said.

NBC News’ Political Director Chuck Todd said the Weiner scandal proved to be a major distraction for Democrats who thought they were making progress on Medicare. Polling before the Weiner news showed the Paul Ryan Medicare plan was dropping in popularity – and Todd said some Democrats saw the 2012 tide turning in their favor because of it.

“They [Democrats] actually think they can win back control in 2012…they don’t have time to be dealing with Anthony Weiner,” Todd said.

Why might Romney might want Texas governor Rick Perry to enter the race?

Does Murray think Michele Bachmann has the longevity to win the GOP nomination?

Todd and Murray point to concrete actions Sarah Palin must take before you can assume she'll run. 

John Huntsman's biggest weakness might be that he seems too much like President Obama. 

Tim Pawlenty's name recognition was up in the poll, but he should still be worried.
