what channels will salute to america be broadcast in its entirety
Fox News Channel was the major cable news network scheduled to air President Trump’s 4th of July “Salute to America” in its entirety in 2019, according to contemporaneous coverage.
What that means
That report said Fox News was the only major cable news network carrying the event end-to-end, while other outlets may have shown highlights or limited coverage.
Current caveat
If you meant a different year’s “Salute to America,” the channel lineup can change by event and by broadcaster, so the exact full-coverage channel list would need to match the specific edition you mean.
