President Trump on Saturday morning ripped into a federal judge's decision to temporarily block enforcement of his controversial travel ban.

“When a country is no longer able to say who can, and who cannot , come in & out, especially for reasons of safety &.security — big trouble!” Trump posted on Twitter.

He also appeared to question the legitimacy of the federal judge who issued the ruling.

“The opinion of this so-called judge, which essentially takes law-enforcement away from our country, is ridiculous and will be overturned!” Trump tweeted.

That's right Pres tell it like it is!
