ORLANDO, Fla. -

U.S. Sen. Bill Nelson (D-Fla.) visited Orlando on Thursday and discussed his proposed legislation to combat ISIS in Syria.

"The leader of ISIS claims that he will have the black flag of ISIS flying over the White House," said Nelson.

At a groundbreaking ceremony for the new VA Simulation Center, Nelson stressed the importance of authorizing airstrikes against the Islamic militant group.

"Now, you've got to go in and go where the head of the snake is.  It's in Syria," said Nelson.

On Tuesday, ISIS released a video showing the beheading of American journalist, and former University of Central Florida student Steven Sotloff.  Since then, Nelson has made it a priority to introduce legislation to authorize air strikes in Syria.

"With American airstrikes, both manned and unmanned, along with coalition forces on the ground, we can stop this evil force that knows no decency," Nelson said.

Nelson also said that President Barack Obama has made the proper decisions regarding ISIS and he's confident that Congress will pass his proposed legislation.

"I cannot imagine a member of Congress denying the authority to go after a group that is this extreme," Nelson said.
