Did our Govt release UFO info to divert our attention from Trump/Putin relationship?

In case you missed it, the Department of Defense has recently admitted that they have been studying UFOs, and they even released a 2004 video of one.  But why tells us now?  I think Tucker Carlson may have let the cat out of the bag, at the 3:55 mark of this interview.  He said that he thought this was a bigger story than Vladimir Putin.  Is the government so desperate to divert our attention from Trump's relationship with Putin, that they are even willing to disclose some of their UFO info?
