U.S. President Barack Obama met with former Secretary of State Hillary Clinton for about an hour on Monday, reports Reuters.

"President Obama and Secretary Clinton enjoy catching up in person when their schedules permit," White House spokesman Josh Earnest told Reuters in an emailed statement. "This afternoon they met privately for about an hour at the White House and discussed a range of topics."

He gave no further details on what they discussed; however, rumors have it Clinton wanted to discuss her alleged 2016 presidential run.

Immediately following the White House announcement about the meeting, Clinton's official account tweeted a photo on Monday of she and Obama preparing to hug, along with a message about the fifth anniversary of the president's Affordable Care Act signing.

"#ACA@5: 16m covered. Young ppl. Preexisting conditions. Women get better coverage. Repeal those things? Embrace them!" she wrote.

Is it a true friendship or a political relationship between the president and Clinton? Both, it seems. In January 2013, when she was leaving her post as his secretary of state, they appeared together on CBS' "60 Minutes." Obama said that he would miss her -- that he was a great "admirer" and they had a great "collaboration."

Above all, he praised her thoughtfulness, discipline and stamina. He referred to her as a "strong friend."

The Washington Post suggests that Obama, with no more elections and little hope of accomplishing much through legislation, may be of some help to Clinton's presidential campaign. For example, the president can bring attention to an issue like family leave, which Clinton can incorporate into her presidential campaign, and Republicans are forced to discuss an issue they'd rather ignore.

Clinton also attended a morning event in Washington hosted by the Center for American Progress where she and Housing Secretary Julían Castro discussed creating more opportunity in America's urban centers.

A formal announcement is pending from Clinton on whether or not she will be the front-runner for the 2016 Democratic presidential nomination. It is presumed that Castro will be her runningmate, according to NBC News.
