Border agents are battling illegal immigration hotspots along the US-Mexico border where cameras have been out of action for up to a year, Report informs referring to Newsweek.
An investigation by Newsweek also reveals that immigration authorities have suggested much of the border's camera network, intended to alert law enforcement officers to illegal crossings, is obsolete and no longer fit for purpose.
One border agent said that the problem has become a "big nationwide issue" as cartels exploit weak points to smuggle undocumented migrants into the country.
Republicans have said the failures are evidence of "wide-open border policies" from the Harris-Biden administration that are fueling human trafficking. The Harris campaign has not responded to Newsweek's requests for comment.
It comes as former President Donald Trump and Vice President Kamala Harris battle to convince voters in November's presidential election that they can tackle the problems posed by the US-Mexico border.
