Democrat Jim Webb told ABC News that he has been getting "a lot of support" as he's exploring a presidential run.
Host George Stephanopoulos asked, "What are you up to, exactly?"
"Well, we're actually truly exploring whether it is possible to conduct a viable campaign in this present environment where money is flooding the political process," Webb said, talking of a possible presidential run.
Senator Tom Cotton of Arkansas explained the reasoning behind the letter he and 46 other senators sent to Iran about the nuclear deal this morning on CBS. Watch Cotton's interview with Bob Schieffer here:
In a Saturday night letter from President Obama's chief of staff Denis McDonough to Senate Foreign Relations Committee chair Bob Corker, the White House confirmed that in fact the United Nations will play a key role in any nuclear deal that may be reached with Iran.
"The United Nations Security Council will also have a role to play in any deal with Iran," McDonough writes, after urging Congress not to pass a bill related to the nuclear negotiations.
Louisiana governor Bobby Jindal is encouraging all candidates -- Democrats and Republicans -- to sign the letter organized by Senator Tom Cotton warning that any Iran deal not accepted by Congress can be revoked.
I support "the letter sent by Senator Tom Cotton and his colleagues to Iran warning them that Congress will have to approve any nuclear deal," Jindal's statement reads.

"So you see, my friends, this deal has two major concessions. One, leaving Iran with a vast nuclear program, and, two, lifting the restrictions on that program in about a decade. That's why this deal is so bad," said Netanyahu.
Susan Rice told AIPAC It was "neither realistic nor achievable" to expect Iran to stop enriching uranium:
"We cannot let a totally unachievable ideal stand in the way of a good deal. I know that some of you will be urging Congress to insist that Iran forgo its domestic enrichment capacity entirely," Rice told AIPAC, as the crowd broke in to chear.
"But, but, but as desirable as that would be, it is neither realistic nor achievable."
Secretary of State John Kerry contradicted National Security Adviser Susan Rice by saying that Israel prime minister Benjamin Netanyahu is "welcome to speak in the United States" and by saying that the U.S.-Israel relationship is at an historic high. Kerry made the comments this morning on ABC:
