All eyes will be fo­cused on net­works and tele­vi­sion sta­tions in the Unit­ed States of Amer­i­ca Tues­day night as the bal­lots are count­ed in what has been one of the most hot­ly con­test­ed elec­tion races in his­to­ry.

US Pres­i­dent Don­ald Trump - a Re­pub­li­can - is be­ing chal­lenged by De­mo­c­ra­t­ic pres­i­den­tial can­di­date and for­mer Vice Pres­i­dent Joe Biden.

The elec­tion to­day has al­ready seen more than 90 mil­lion Amer­i­cans vot­ing ahead of the of­fi­cial elec­tion day.

On Mon­day, Trump con­tin­ued his fre­net­ic pace of cam­paign­ing in North Car­oli­na, Penn­syl­va­nia, Wis­con­sin and Michi­gan.

His De­mo­c­ra­t­ic ri­val Biden cam­paigned in Penn­syl­va­nia and Ohio.

Biden was joined by pop star La­dy Gaga at a ral­ly in Pitts­burgh, while singer John Leg­end ap­peared with run­ning mate Ka­mala Har­ris in Philadel­phia.

The US is on course for its high­est elec­toral turnout rate in more than a cen­tu­ry.

The fi­nal push for votes fol­lows Amer­i­ca’s worst ever week for new coro­n­avirus cas­es, with more than 1,000 peo­ple dy­ing each day.

The FBI said yes­ter­day it was in­ves­ti­gat­ing af­ter a con­voy of ve­hi­cles with Trump flags sur­round­ed a bus car­ry­ing Biden cam­paign staff on a Texas high­way.

There have been mount­ing fears of elec­tion vi­o­lence af­ter Trump said there may not be a smooth tran­si­tion of pow­er if he los­es the elec­tion.

Al­ready, one of the coun­try’s biggest re­tail stores Ma­cy’s board­ed up its flag­ship store in Mid­town New York.
