NOTABLES

• WHAT SHE DIDN'T SAY: Hillary Clinton was likely hoping to put the issue of her use of a private email account as Secretary of State to rest by hosting a news conference, but more than a few questions remain unanswered. She said yesterday that the reason for the use of one, personal account was "convenience," though that does not explain the issue fully. ABC's JONATHAN KARL had the latest on "Good Morning America" today: http://abcn.ws/1wXypDt And ABC's MEGHAN KENEALLY highlights some of the questions that remain unanswered following Clinton's news conference: http://abcn.ws/189kFcX

-WHY DID SHE DELETE HER PERSONAL EMAILS? Clinton argued that she had a number of emails about personal issues that should not be considered part of the public domain. "No one wants their personal emails made public, and I think most people understand that and respect that privacy," Clinton said.

-HOW DO WE KNOW WHAT SHE DELETED? Clinton's word is really the only check that the public will have on this front. The emails that she chose not to keep included emails "about planning Chelsea's wedding or my mother's funeral arrangements, condolence notes to friends, as well as yoga routines, family vacations, the other things you typically find in inboxes," she said.

-WILL THE PUBLIC EVER KNOW WHAT EMAILS SHE SENT? Yes, but only the emails that Clinton and her team have deemed related to her work as Secretary of State, and then from there, only what the State Department approved. State Department spokeswoman Jen Psaki said that once cleared, the 55,000 pages of emails that Clinton handed over will be shared publicly on a government website though not for several months. When it comes to her personal emails, the public will never know. Yesterday, Clinton ruled out an independent review of her server.

• HILLARY CLINTON DIDN'T USE 2 PHONES AS SECRETARY OF STATE - BUT SHE DOES NOW: When Hillary Clinton began her term as secretary of state in 2009, she thought it would be "easier," "better," "simpler" and more convenient to "carry just one device for my work and for my personal emails instead of two," she said repeatedly at yesterday's news conference, with slight variations in wording. But these days, she uses two devices. Clinton acknowledged as much just two weeks ago at the Silicon Valley Conference for Women in response to a question from Re/code's Kara Swisher. http://abcn.ws/1E9TxpN

• ANALYSIS - ABC's SHUSHANNAH WALSHE: Hillary Clinton was greeted this morning with some rough editorials and headlines, including the New York Posts's screaming "Deleter of the Free World" front page. She and her team were hoping yesterday's press conference would put this issue to rest, but it doesn't seem to have done that at all, instead bringing up even more questions. Questions she is hoping Americans buy her answers to, including why she chose to delete 30,000 e mails she described as personal. She explained yesterday saying "no one wants their personal e mails made public, and I think most people understand that and respect that privacy." She's betting that voters agree with her and don't care or forget before the campaign really heats up, but it's likely this issue isn't going away anytime soon so is that even possible with an announcement likely as soon as next month?

WHY SOME THINK 47 GOP SENATORS BROKE THE LAW WITH IRAN LETTER. Some law professors and liberal commentators say they believe the "open letter" Sen. Tom Cotton and 46 of his Republican colleagues sent this week to the leaders of Iran, warning them that any nuclear deal they sign with President Obama won't last after Obama leaves office, might be a crime. That letter from the Arkansas Republican to the ayatollahs and other Iranian officials, critics say, is a violation of the 1799 Logan Act. "This [letter] seems squarely to satisfy the elements of the law," Temple University law professor Peter Spiro declared, suggesting a crime has occurred here. But hold on. In the 215-plus years the Logan Act has been on the books, there's only been one indictment against someone for breaking the law, in 1803, and the case fell apart before trial. And what the GOP senators are doing here, while rare, is hardly unprecedented. Here's the full analysis by ABC's TERRY MORAN. http://abcn.ws/1B22RXZ

GOWDY WILL CALL ON CLINTON TO APPEAR AT BENGHAZI SELECT COMMITTEE. Rep. Trey Gowdy, the chairman of the House Select Committee on Benghazi, reacted to Clinton's news conference in a written statement Tuesday, noting that he's left with only more questions. As a result, he said he will invite her to appear at the committee at least twice - although he pledges to make only the second one public, ABC's JOHN PARKINSON reports. "The first appearance will be to clear up her role and resolve issues surrounding her exclusive use of personal email to conduct official business. This is necessary to establish our Committee has a complete record with respect to Secretary Clinton's time in office," Gowdy said in a statement. "Our committee will then call her to appear before the Committee in a public hearing to answer questions specifically regarding Libya and the Benghazi terrorist attacks that took the lives of our four brave fellow citizens." The dates for these appearances have not yet been announced.

FEINSTEIN ON GOP IRAN LETTER: 'WORST THING I'VE SEEN SINCE I'VE BEEN HERE.' Sen. Dianne Feinstein, D-California, didn't mince words when asked for her thoughts on the Republican letter to Iranian leaders: "It's about the worst thing I've seen since I've been here, to be candid with you." Calling the letter "atrocious" and "unprecedented," the ranking Democrat on the Senate Intelligence Committee, accused Senate Republicans of seeking to prevent a nuclear deal with Iran without offering a viable alternative, increasing the likelihood of a military strike of some sort in the future, ABC's GREG HUGHES notes.

GRAHAM RESPONDS TO PRESIDENT ON IRAN LETTER. Sen. Lindsey Graham used his remarks to the International Association of Firefighters conference yesterday to rebut President Obama's statement to the senators that signed the letter to Iran. Graham pointed out the president's line that the senators were empowering the hard liners by deviating from the administration's effort to negotiate. "Mr. President, There are no moderates running Iran, the moderates were out in the street several years ago and they got killed," he said, after calling radical Islam acquiring a weapon of mass destruction one of the two greatest threats to America. "I would like to end their nuclear ambitions peacefully through diplomacy if at all possible," Graham said, but added that Iran is lying if they say they aren't trying to get a nuclear weapon, ABC's STEPHANIE EBBS writes.
