Special Agent Leroy Jethro Gibbs meets First Lady Michelle Obama as the FLOTUS is set to appear on “NCIS” next month.

Mrs Obama will appear as herself on an upcoming episode of the CBS procedural drama. The episode will feature the Joining Forces initiative that she co-founded with Dr Jill Biden, the wife of Vice President Joe Biden, in 2011, Entertainment Weekly reported.

The Joining Forces aims to support service members, veterans, and their families by providing education opportunities, employment resources, and access to wellness programmes.

The NCIS episode will be set in the White House, as First Lady Obama welcomes Gibbs (Mark Harmon) and the wife of a Marine for a Joining Forces roundtable. The extras in the scene will be made up of actual military spouses, EW noted.

Mrs Obama has been known to be very active in raising awareness on several initiatives and she appeared on various TV shows for these.

In 2014, she was on the Disney Channel series “Jessie” to promote Joining Forces and she also had a cameo on NBC’s “Parks and Recreation” in support of the Let’s Move effort to solve the problem of childhood obesity, USA today reported. NCIS is the first TV drama for the FLOTUS.

NCIS executive producer Gary Glasberg told USA Today that Obama’s scene was initially planned to be shot on the show’s set in California, but schedules changed. The First Lady then invited the series to film at the White House instead.

Glasberg thanked Mrs Obama for her “warm and welcoming” involvement and says NCIS is the first dramatic programme to film inside the US First Family residence. Most of the filming took place in the Blue Room.

“I brought a crew and we spent a day in the White House, It was a dream come true for all of us. We feel honoured and privileged,” he said.

“NCIS” episode with FLOTUS, titled “Homefront,” will air Tuesday, May 3 at 8 p.m. ET on CBS.

It was earlier reported that actor Michael Weatherly, who played very special agent Anthony DiNozzo, is saying goodbye after 13 years in the series.
