Huawei's 2018 hasn't gotten off to a great start, with both AT&T and Verizon reportedly dropping plans to offer Huawei's flagship Mate 10 Pro, and now Huawei's bad year is continuing.

Six US intelligence chiefs have said that Americans should use Huawei products. This group included the heads of the CIA, FBI, and NSA, as well as the director of national intelligence.

Here's what FBI Director Chris Wray said to the Senate Intelligence Committee:

"We're deeply concerned about the risks of allowing any company or entity that is beholden to foreign governments that don't share our values to gain positions of power inside our telecommunications networks.

"That provides the capacity to exert pressure or control over our telecommunications infrastructure. It provides the capacity to maliciously modify or steal information. And it provides the capacity to conduct undetected espionage."

In response, Huawei explained that its products are used by governments and consumers in 170 countries around the world and that it "poses no greater cybersecurity risk than any ICT vendor."

Near the end of 2017, rumors said that Huawei's new Mate 10 Pro flagship would be sold on AT&T and Verizon in the US. That would've given Huawei's presence in the US a huge boost, as most US consumers buy their phones from their carriers but Huawei has largely only been selling its devices unlocked. However, it's said that AT&T and Verizon backed out of those deals at the last minute due to pressure from the US government.

The unlocked Huawei Mate 10 Pro is now available for pre-order in the US ahead of its February 18 launch.
