The order blocking the ban was issued yesterday by Seattle US District Judge James Robart and is valid across the US, jeopardizing Trump's stated plan to prevent radical Islamic terrorists from entering the country.
"The opinion of this so-called judge, which essentially takes law-enforcement away from our country, is ridiculous and will be overturned!" Trump said in his early morning tweet to his 23.6 million followers.
"Interesting that certain Middle-Eastern countries agree with the ban. They know if certain people are allowed in it's death & destruction!" Trump said.
Trump's executive order, which went into effect a week ago, blocks citizens of Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen from entry into the US for 90 days, while barring entry of Syrian refugees indefinitely, and refugees from other countries for 120 days.
