That's exactly what he did.
Check out this 1/1/17 AP article:
WASHINGTON (AP) As Barack Obama began preparing to leave office, the first smartphone-toting U.S. president ordered his team to upgrade the White House's aging technology for his successor. New computers were purchased and faster internet was installed.
All of those machines should be diagnosed for bugs, documented, and then scrapped.
Gee, wasn't that nice of him. What a swell guy.
What a waste of money.
The Trump team needs to use the newest and most effective technology hardware/software and sweep the entire white house for listening/video devices.
And either get a top notch team of forensic experts to vet every computer or them them out.
It will probably be easier and less expensive to replace the computers.
The newly installed Obama computers need to be reprogramed so the Trump admin can watch them. And then make sure they all go into democrat hands.
Give some to the DNC and every democrat in congress. It's quite obvious that Obama had this done to compromise Trump's admin.
