Sen. Rand Paul (R-Ky.) said Wednesday that he believes the estimated costs for President Donald J. Trump’s U.S.-Mexico border wall are just too high to justify. Paul said that while he supports additional barriers at the border, he’s not “excited” about spending billions to do it.

“I remain a fiscal conservative, even on the wall, so I’m not excited about spending $20, $30, $40 billion on a wall. I’m still a believer that we don’t have money to spend. We’re $700 billion in the hole,” Paul told CNN’s Wolf Blitzer in an interview (see below).

“And while I will vote for money for barriers, I’m not voting for $40 billion for barriers,” Paul clarified.

Paul said including strategic barriers win a security plan is advisable, however the price to install those barriers should be debated, and he believes more emphasis should be placed on technology to improve border security, rather than physical barriers, as a cheaper option.

“The barriers, I think we need to look at the cost of them. The people advocating for it are forgetting they’re fiscally conservative and are just giving enormous numbers,” Paul added.

Paul’s figures come from reports that Trump administration is seeking $33 billion to increase southern border security. Trump’s plan, according to reports, is to seek from Congress $18 billion to fund the border wall and $15 billion to fund technology, personnel and other improvements.

An additional $8.5 billion will be sought to pay for 5,000 new Border Patrol agents over the next seven years.
