Got a link to back up your claims, both about the approval and funding, and that Obama illegally stopped the wall from being built?

Obama Administration Ends High-Tech Border Fence
Your first link goes to talk about the Secure Fence Act, and incidentally, it was 99.5 percent completed in 2011. Here's what Wikipedia says about it........
Erection of the fence
By April 2009, DHS had erected about 613 miles (985 km) of new pedestrian fencing and vehicle barriers along the southwest border from California to Texas.[6] Delays frustrated some, such as Senator Jim DeMint, Republican of South Carolina, who in 2010 introduced legislation seeking to require completion of the 700-mile-long, double-layered fence. (DHS had since 2007 begun to "to shift its focus to erecting a 'virtual fence' along the 2,000-mile border, using sensors, cameras and other high-tech equipment to prevent illegal crossings."). DeMint's legislation was defeated in a 52-45 Senate vote in 2010.[7]
By May 2011, DHS reported completing 649 miles of fencing (99.5% of the 652 miles planned). The barrier was made up of 299 miles of vehicle barriers and 350 miles of pedestrian fence.[5] The fencing includes a steel fence (varying in height between 18 and 26 feet) that divides the border towns of Nogales, Arizona in the U.S. and Nogales, Sonora in Mexico.[8] A 2016 report by the Government Accountability Office confirmed that the government had completed the fence by 2015.[9] A 2017 GAO report noted: "In addition to the 654 miles of primary fencing, CBP has also deployed additional layers of pedestrian fencing behind the primary border fencing, including 37 miles of secondary fencing and 14 miles of tertiary fencing."[10]
Cost
Although the 2006 law authorized construction of a fence, Congress initially did not fully appropriate funds for it (see authorization-appropriation process). "Congress put aside $1.4 billion for the fence, but the whole cost, including maintenance, was pegged at $50 billion over 25 years, according to analyses at the time."[9]
A 2017 GAO report noted: "According to CBP, from fiscal year 2007 through 2015, it spent approximately $2.3 billion to deploy border fencing along the southwest border, and CBP will need to spend a substantial amount to sustain these investments over their lifetimes. CBP did not provide a current life-cycle costs estimate to maintain pedestrian and vehicle fencing, however, in 2009 CBP estimated that maintaining fencing would cost more than $1 billion over 20 years."[11]
Secure Fence Act of 2006 - Wikipedia
So, we already know that 99 percent of the fence was put up by 2011. Obama was elected in 2008, so exactly HOW did he stop the Secure Fence Act? Incidentally it wasn't fully funded by Congress, and it was less than 700 miles long.
As far as Obama stopping the border fence? It wasn't that one, and both your links on this go to the same page. Here's what your link says about that one.......
WASHINGTON - The Obama administration on Friday ended a high-tech border fence project that cost taxpayers nearly $1 billion but did little to improve security. Congress ordered the high-tech fence along the border with Mexico in 2006 amid a clamor over the porous border, but it yielded only 53 miles of protection.
Homeland Security Secretary Janet Napolitano said the lesson of the multimillion-dollar program is there is no "one-size-fits-all" solution for border security.
Napolitano said the department's new technology strategy for securing the border is to use existing, proven technology tailored to the distinct terrain and population density of each region of the nearly 2,000-mile U.S-Mexico border. That would provide faster technology deployment, better coverage and more bang for the buck, she said.
The low tech fence authorized by Jr. was built. The additional high tech fence that Congress authorized in addition was stopped because it didn't provide enough security for the cost.
You're mixing apples and oranges dude.
