The Biden administration is quietly selling off parts of Donald Trump's border wall to try to thwart Republicans who want to force it to be extended.

A website called GovPlanet, which offers online auctions for military surplus, listed hundreds of unused parts of the southern barrier in recent months.

Since April 81 steel square structural tubes - which would have been used within the wall's 30ft panels - have been sold for a profit of $2million.

On Tuesday officials sold over 700 28ft hollow beams in five separate lots for $212 each. Over a dozen are also up for grabs at auctions over the next two Tuesdays.

It comes despite the Democrat-led Senate voting through part of a Republican-sponsored bill that would bring about extending the wall.

Meanwhile most Americans support completing it, according to a DailyMail.com/TIPP poll that shows broad support for the Trump policy.

Some Republicans accused President Biden of rushing to sell the materials before the GOP-led House could pass a matching version of the Senate bill.

'President Biden cannot get away with subverting Congress’ work on this — he must put the border materials to use,' said. Sen. Joni Ernst, R-Iowa.

Adverts for the auctions were posted on the Gov Planet website over the past week showing the huge steel structures on the ground.

One listing had 162 nucor tubes on the market for $29,000, which the site later updated to having been sold.

The listings had a series of photographs showing the measurements of the items for sale and images of them scattered about near the southern border.

It comes as Biden is under fire from Republicans for avoiding the southern border while on official travel last week to border states Arizona and New Mexico.

The president's stop in Arizona coincided with a border field hearing put on by House Oversight Committee Republicans in the same state - in Cochise County.

The GOP lawmakers slammed their Democratic colleagues for refusing to participate and also criticized the administration's inaction on the border crisis.

Months after Biden brought in new immigration policies they said would reduce the number of migrant crossings, last month the surge saw signs of returning.

Rep. Glenn Grothman, R-Wis., opened the hearing by stating that 'none of my colleagues on the other side of the aisle have decided to join us today, despite an open invitation to participate.

'You cannot know what is going on at the southern border unless you've been here and talked to the people who live it,' the subcommittee chairman continued.

'While [President Biden] is also currently in Arizona, securing our border is once again at the bottom of his priorities. It remains at the top of mine,' tweeted Rep. Chuck Edwards, R-N.C., who shared a video of himself closing the border wall gate.

'More helicopter 'leadership' from President Biden,' tweeted Rep. Darrell Issa, R-Calif. 'Visiting Arizona and New Mexico and yet no time for a visit to the border crisis he created.'

Cochise County Sheriff Mark Dannels told Republicans during the hearing cartels are using social media to recruit Americans, including teens, to become 'getaway drivers.'

Several of the lawmakers accompanied Sheriff Dannels to survey the border wall in the sector that sees a 'disproportionate amount of the illicit fentanyl' enter the U.S.

Another main issue in Cochise County is the high number of 'military-aged men dressed in camo crossing in the dead of night,' say Republicans.

They do not willingly turn themselves in to authorities and therefore put law enforcement at risk during high-speed chases.

The hearing also occurred following reports Tuesday morning that heavily armed Mexican cartel members crossed the border into Texas - and have yet to be apprehended.

Biden's trip to the border states also comes as over 6,000 illegal migrants were apprehended by the Border Patrol Tuesday in the Tucson, RGV and Del Rio sectors.

In addition, Border Patrol is holding migrants in an outdoor cage in the Arizona desert as officers try to cope with the surge of people crossing illegally from Mexico.

DailyMail.com pictures show people crammed onto narrow benches as they seek out shade to protect them from the burning sun in a region where temperatures cam hit over 113F.

The site is in the remote desert, about two hours west of Tucson, Arizona. The area is at the heart of a surge in migrant arrivals, undermining Biden administration hopes that its new immigration restrictions are having an impact.

The Republicans seeking their party's nomination in an attempt to replace Biden who once eschewed the border wall have now embraced it.

They include one-time skeptics former UN ambassador Nikki Haley and former New Jersey governor Chris Christie.

Former President Trump's wall that would attempt to slow illegal migration from Mexico to the US has always been controversial — not least when Trump first floated the idea during his 2016 presidential election campaign

The move could be seen as an attempt to slow attempts to extend the wall, which the Democrat-led Senate voted to do as part of a Republican-sponsored bill in the annual defense appropriations bill

Completing the wall is front and center of Florida Gov. Ron DeSantis' 'no excuses' plan to get non-legal immigration under control.

For Vivek Ramaswamy, the third-placed Republican hopeful, the wall is 'not enough,' he told Fox News.

As president, he would bolster the barricades with US military personnel fighting the cartels, drug smugglers and people traffickers.

Meanwhile, Trump, by far the party's front-runner, says he always had the right border security strategy.

At a campaign rally in Erie, Pennsylvania, last month, he trumpeted the 'nearly 500 miles of border wall' erected during his administration.

Trump's numbers are disputed — PolitiFact says he only added 52 miles of new wall, and merely upgraded or reinforced 458 miles of barrier.

But our survey of nearly 1,400 US adults shows why most Republican candidates have wall-building in their manifestos — it's almost universally popular among the GOP base.

Fully 87 percent approve of more construction along the nearly 2,000-mile US-Mexico border.

Even a third of Democratic voters want the barricade finished — a sign that fears of unchecked immigration cross partisan lines and will likely play a key role in the 2024 election.

Illegal crossings along the US southern border jumped more than 30 percent in July, according to US Customs and Border Protection data obtained by The Washington Post earlier this month.

The more than 130,000 arrests at the frontier last month marked an uptick from 99,545 in June — a blow to President Joe Biden's new immigration strategy introduced as pandemic-era enforcement rules lapsed.

New York City Mayor Eric Adams' office this week warned that the number of people coming to the city is still rising.

The Democratic mayor says more than 100,000 have arrived in the city, racking up a more than $12 billion bill for providing food, shelter and other services.
