(CNN) – As the nation's top diplomat, Hillary Clinton used to be a regular presence at the White House, but since leaving her post as secretary of state earlier this year, Clinton has been busy delivering speeches and launching her post-government initiatives.
On Monday, however, Clinton made a return to the building for lunch with President Barack Obama.
Plenty of issues – ranging from health care to Middle East peace talks – could have been conversation starters for the pair, though on Monday, Deputy Press Secretary Josh Earnest said it was "largely friendship that's on the agenda for the lunch today."
"Much has been written about over the last four years how Secretary Clinton and the president have developed not just a strong working relationship, but also a genuine friendship," Earnest said, adding the lunch was an "opportunity for the two, who saw each other on a pretty frequent basis over the course of the last four years, to have the chance to catch up."
Clinton will also meet with Vice President Joe Biden Tuesday at his residence, the Naval Observatory, Clinton aides, as well as a White House official, told CNN. One person with knowledge said the meeting was "long scheduled."
As for her Monday meeting with Obama, Earnest said the president invited Clinton to the lunch, which had grilled chicken, pasta jambalaya and salad on the menu.
Current Secretary of State John Kerry was spotted arriving at the White House around the same time as Clinton, though Earnest said he believed Kerry did not join his predecessor and Obama for the lunchtime meeting. Clinton, however, did stop by to say hello while Kerry met with National Security Adviser Susan Rice, according to Clinton aides.
The White House is preparing for Middle East peace negotiations in Washington Monday night, and Earnest indicated it was more than possible that the talks could have come up come during the meal.
"The purpose of the lunch was chiefly social, but given that the president and Secretary Clinton worked on this pretty closely together over the course of the last four years, I'd be surprised if they didn't," he said.
According to Clinton aides, the lunch came together when Obama and Clinton saw each other at the George W. Bush Presidential Center dedication ceremony in April, where Obama and former President Bill Clinton gave brief remarks. With the president and the former secretary of state having busy schedules this summer, July 29th became the agreed upon date, the aides said.
Former rivals during their marathon battle for the 2008 Democratic presidential nomination, Obama and Clinton forged what most parties say was a strong working relationship during her years at the State Department. Since her departure, the pair met for dinner at the White House along with her husband, and for the dedication of the Bush library in Texas.
Clinton, a potential candidate for the White House in 2016, has spent her months post-State appearing at events focused on women's empowerment, as well as maintaining a healthy roster of paid speaking engagements.
She launched an initiative through the Clinton Foundation dedicated to early childhood development, and signed a book deal in April for a diplomacy-centered memoir to be released in 2014.

Usually a book.deal means no more public office. She could win with the women vote
I'm sure everything from Egypt, Mid-East peace talks & 2016 will be discussed. The biggest political news I've seen over the weekend was the Kentucky Senate candidate Alison Grimes' ad going at Mitch McConnell. Can you say "Shot Fired?" You better be scared Mitch. You better be very scared!!!
Wow. They met for lunch? Stop the presses! News much?
Asked if she would like to watch the gop bloodbath next spring... sure I will bring the popcorn
"No other details of the pair's meeting were provided, though plenty of issues – ranging from health care to Middle East peace talks – could be conversation starters"
In other words, you don't have a story.
Let us know when you do.
Not unusual. Good to see these two working together. And good to see Hilary working for women's issues, women being 52% of registered voters.
The last thing we need is Bill Clinton running around the White House as the "First man" assaulting all the female interns.
As for Obama's latest road shows and fiery speeches, if the President really wanted to get something done for the country, he would be back in DC sitting down with republicans in private doing some serious fence mending and negotiating. But, Obama likes to make fiery partisan speeches. I mean common sense tells us all that you do not poke a stick in your adversary's eye and then ask for something. Obama has been, and never will be a deal making politician and that is why he can never get anything done. And with Pelosi and Reid as his top two in Congress, there is NO HOPE for the Dems to reach across the aisle and make some progress on the important issues of the day. Obama believes his fiery speeches along will move the Republicans to work with him - never gonna happen. And since Hillary is cut from the same mold as Obama, the absolute worst thing for this country would be to put her in office as President. That move would take this county into recession and further alienate Dems and Republicans – with the lower and middle class paying the price for the Democratic political war mongering and public negativity. One of the greatest Speakers of the House was Tip O'Neil of Massachusetts.
Great news. Yes on Hillary16.
Time to get the Benghazi story down so that they can play the music from the same sheet.
Is that what they call it now..."doing lunch?" Why can't they both just admit they have a physical relationship and be transparent.
These two were made for each other...Obama should divorce Michelle, Bill do the same with Hillary, then the Obama and Hillary should elope together and get hitched!
Clinton will win in a landslide in 2016, the GOP has nothing except obstruction and bs.
I wonder if they'll discuss the the dead Americans from their Benghazi cover up?
Whitewater, Vincent Foster, Benghazi. . . .Hillary never takes blame for anything. I'd love to know her secret.
Did Hillary have to pay the OFA $40,000 for the exclusive lunch with Barack?
Hey Hil: I hope you get a choice of your lunch menu. I would not want fried chicken and watermelon for my meal. Go for the lobster salad!!!!!
Hillary Clinton for president 20016
Two of the people I most admire .. Hillary Clinton and President Obama.
When these two get together it can only be bad for all of us. #coverup
Hillary Clinton for president 2016
Egomaniac Billary Clinton has been gearing up for her run for the presidency ever since 2008. She's a disgusting, cynical self-serving boor. The term limits for office should include one's spouse. We don't want the Clintons and their lack of morality in the White House again.
Talking about Chris Stevens no doubt
I guess they are seeing what else they need to cover up.
Hillary: "You know I'm planning on running in 2016, so could you refrain from throwing me under the bus for the rest of your term? Now eat your vegetables young man."
Why does the name Clinton seem to be synonymous with scandals? She would be the worst choice for a Democrat Presidential candidate ever.
