President Trump said Wednesday he would block portions of the border wall that California wants built now until the funding for the entire southern wall is approved and funded.

“I have decided that sections of the Wall that California wants built NOW will not be built until the whole Wall is approved. Big victory yesterday with ruling from the courts that allows us to proceed. OUR COUNTRY MUST HAVE BORDER SECURITY!,” Trump tweeted.

Trump was referring to his Tuesday court victory, in which a federal judge Trump once disparaged as being Mexican agreed that the administration has the right to waive environmental laws to start building the border wall.

Trump didn't specify which parts of the wall that California wants to build today. But sections of the border wall that does exist in pieces in the state are reportedly being repaired and replaced, and Trump's warning on Wednesday could be a sign that he will try to stall those efforts until the entire wall is approved.
