Of the southern wall materials, those that were sold by the biden/harris administration, how far in miles would the materias had built, if applied to the construction of building the S. wall?

1. What the public record actually shows about the sales

Multiple outlets report that leftover wall components were moved to auctions or transferred to border states after Congress and the National Defense Authorization Act required a disposition plan; reporting by AZCentral and others says roughly 60% of covered materials were transferred and about 40% were sold through competitive sales contracts, and fact‑checking outlets note the sales began under legal requirements enacted in late 2023 ^{[1] [2] [3]}.

2. The recurring 20‑mile reference and what it means

Several stories tie at least one tranche of sold materials to projects or stockpiles associated with a roughly 20‑mile contract the Biden administration later approved to complete barriers in Texas, but those accounts describe timing and proximity rather than a precise materials‑to‑mileage accounting; Newsweek reported materials “meant” for a 20‑mile stretch, and similar language recurs in Newsweek and other coverage, but none of those pieces publishes a contractor inventory converting the sold items into linear miles of wall ^{[4] [5]}.

3. Why a simple miles calculation is not available from reporting

Converting sold pieces into miles requires at minimum (a) a disclosed total count of panels/pickets/18–28‑ft beams sold, (b) specification of which panel/picket design those items would complete, and (c) installation spacing and ancillary hardware needs; public reports cite lot counts, auction sales and anecdotal descriptions (for example, references to lots of 28‑foot hollow beams), but they do not provide a full materials manifest that would let independent reporters calculate an accurate linear distance that could have been built ^{[6] [1] [3]}.

4. Plausible scenario math — what the reporting allows as an estimate

If one assumes the auctioned materials were the same pool tied to the 20‑mile procurement discussed in several reports, then selling 40% of that covered stock implies about 8 miles’ worth of material (40% of 20 miles = 8 miles) — an arithmetic inference based on the sale fraction reported, not on a physical inventory ^{[1] [4]}. That scenario is transparent about its premise: it converts a reported percentage of disposal into linear miles only by assuming the underlying materials were exclusively earmarked for the 20‑mile project referenced in news reports.

5. Counterclaims, legal actions and political framing

Republican officials and conservative outlets framed the auctions as deliberate sabotage of a Trump‑era construction program and in some cases claimed rapid daily removal rates (e.g., up to “one half mile per day”), while fact‑checkers and legal reporting emphasize the sales complied with statutory disposition requirements and that litigation temporarily blocked further disposals — these competing framings affect public impressions but do not, in the public record cited, produce the missing manifest needed for a firm mileage calculation ^{[7] [8] [9] [3]}.

6. Bottom line and reporting limits

The verifiable bottom line from available sources is that roughly 40% of the identified “covered materials” were sold and that some of those materials have been linked in reporting to a 20‑mile project footprint; the direct conversion of sold items into a precise number of miles built is not possible from the documents and news accounts reviewed because no publicly released, itemized inventory links sold lots to the exact components needed per linear foot of wall ^{[1] [4] [3]}. Any more granular claim about exact miles built by the sold materials would require disclosure of government inventories or contractor records not present in the cited reporting.
