The thing is, that part is not true and made up bull crud by Trumper lying media....like zerohedge, or the gateway pundit etc...
The homeland security report, was an automatic computer generated report. The Tennessee officer never was told by homeland security or FBI or whomever Trumpers are lying about in the Biden admin, to not arrest him.... No one at homeland security was spoken to the night of the stop incident for speeding. It was 5 days later that a human in homeland security even looked at the automated, computer generated form.
