WASHINGTON, D.C - Oklahoma Congressman Jim Bridenstine may be one step closer to becoming the head of NASA. A motion filed Monday moves his confirmation vote forward.

President Donald Trump nominated Congressman Bridenstine to oversee NASA last year, but his confirmation has been held up by some lawmakers who believe Bridenstine may not be the best candidate for the job.

Republican senate floor staff say Majority Leader Mitch McConnell filed a motion Monday to move forward with his nomination vote. Democrats have all said publicly they will not support Bridenstine, over concerns about global warming and lack of experience.

Florida Senator Marco Rubio had also previously opposed him. But Monday's motion could be an indication someone flipped, and McConnell believes Bridenstine has the votes needed to confirm him.

It's not clear yet when the Senate would vote, but it's believed the vote could come as early as this week.
