SCOOP: Trump budget chief Vought tells GOP senators $175B needed 'immediately' for border security

In his presentation, Vought detailed what the administration requires for "robust and sustained" border security and immigration enforcement, according to the official. 

The funding being sought would go toward ramping up personnel across agencies, expanding detention capacity and reinstituting the "Remain in Mexico" program. 

It would also include border wall construction and building border infrastructure, deploying innovative surveillance technology to the border, deporting migrants, military support for deportation operations, enhancing the Coast Guard's role in border enforcement and giving state and local governments the financial and operational resources to deal with the effects of large-scale illegal immigration, per the official. 

This was relayed to the Republican senators by Vought during the GOP lunch. 

The $175 billion topline request has already been factored into Senate Committee on the Budget Chairman Lindsey Graham's reconciliation bill, which is slated to go through the key committee this week. 

Initially, House Republicans were expecting to take the lead on reconciliation, and they wanted to do so with a one-bill approach, addressing each Trump priority altogether. But the lower chamber's pace quickly frustrated senators, prompting Graham and Senate Majority Leader John Thune, R-S.D., to press forward with their plan. 

"Even if the price of some of these measures may seem high, they are nothing when compared to the costs our country is facing in the long term of continuing the status quo," they said of the pressing need.
