Editor's note: the above video was first created in April 2018 when T-Mobile and Sprint announced they agreed to the merger. 

T-Mobile’s proposed $26 billion merger with Sprint is facing a roadblock from the U.S. Department of Justice, according to a new report from the Wall Street Journal.

Justice Department officials warned the companies that their merger isn’t likely to receive approval under the current proposal, anonymous sources told the Journal.

Their entreaty to regulators also claims that merging will increase American competitiveness in the next generation of wireless technology known as 5G.
