The Trump family's latest venture, an "America first" mobile network and self-branded phone will "eventually" be built in the U.S., leaving questions about where the new "T1" phone will be manufactured ahead of its launch later this year.

"Making phones in America. It’s about time we bring products back to our great country," President Trump's son, Eric Trump, said while talking about the device.

The phone will also come alongside a mobile phone service with a monthly fee of $47.45.
