Conservative commentator Ann Coulter ripped President Trump on Wednesday for focusing on tax reform instead of the border wall on the U.S. Mexico border during his speech in Missouri.

"WTF! Why is @realDonaldTrump back to tax cuts? His election was NOT about tax cuts. Has he been talking to @SpeakerRyan again?," Coulter tweeted.

Coulter has been a vocal supporter of Trump's immigration policies but has been critical of him of late for not pushing more forcefully for his promised border wall.

"This isn't a 'once in a lifetime' shot at tax cuts! EVERY GOP cuts taxes! This is 'once in a lifetime' shot to save US: Wall & deportations!," Coulter said in another tweet.

She continued her criticism of Trump and Republican leadership in a flurry of tweets.
