President Obama forgot to return the salute of a U.S. Marine while boarding Marine One Friday morning, then came back out to shake the Marine’s hand, according to a tweet by CBS News’ Mark Knoller.

The timing was particularly awkward because Marine One was about to whisk Mr. Obama away to Annapolis, Md. to give the commencement speech at the U.S. Naval Academy commissioning of U.S. Navy and Marine Corps officers.

Mr. Obama later chatted with the Marine and gave him another hand shake just for good measure, Mr. Knoller tweeted later.

The exchange comes after the president riled some Marine Corps officers last week by asking Marines to hold umbrellas over him and Turkish Prime Minister Erdogan so they wouldn’t get wet while they were giving a press conference in the White House’s Rose Garden. Marine Corps regulation prohibit Marines from carrying umbrellas while in uniform.

Later Friday morning, Mr. Obama was forced to endure light rain sans umbrella while delivering the commencement speech to roughly 1,000 midshipmen.

His efforts to make light of the situation fell a little flat, considering last week’s umbrella incident.

“I know it’s a little wet but the superintendent told me that folks in the Navy and Marine Corps don’t mind a little water,” he said to tepid laughter.
