President Barack Obama has spoken with members of the U.S. team which raided and killed Osama bin Laden on Sunday after arriving earlier at Ft. Campbell in Kentucky.

Obama went straight to private meetings with the team after arriving, White House spokesman Jay Carney told reporters on the base.

The U.S. team of Navy SEALs who raided bin Laden's compound in northern Pakistan in helicopters were on the site for less than 40 minutes and did not encounter any local authorities during the raid, a senior Obama Administration official said earlier in the week.

U.S. officials say bin Laden was unarmed when he was killed.

Even if bin Laden had tried to surrender, there would be a good basis on the part of those very brave Navy SEAL team members to do what they did in order to protect themselves and the other people who were in that building, said Attorney General Eric Holder on Wednesday before a Senate committee where he argued that the killing was legal.

The President arrived along with Vice President Joe Biden and went to an undisclosed location at the airfield.

The pair will have the opportunity to hear from and thank some of the special operators involved in the operation, a White House official said.

Afterwards, Obama is set to speak to about 2,200 soldiers and base personnel.

Banners on the wall in the hangar where the president will speak read Job well done, Fort Campbell, home of the screaming eagles and Welcome home.

A huge U.S. flag hangs in the backdrop of the podium, according to the report.
