With the victory in Arizona, Donald Trump has won another swing state and amassed 11 electoral votes.
The victory was declared by US media on Saturday night following four days of counting in the southwest state.
In addition to Pennsylvania, Michigan, Wisconsin, Georgia, North Carolina, and Nevada, which he reclaimed on Saturday, Arizona is now the seventh and last state that Mr. Trump has regained for the Republican Party.
In 2020, Mr Trump lost the battleground state, which he won in 2016, to president Joe Biden. Arizona went on to have a Democratic governor and senators.
Before 2020, the state had been a GOP stronghold. Immigration and border security were key issues during the 2024 election, with Arizona boasting the fourth-largest Hispanic voting population. Mr Trump visited during his recent campaign and turned the tide.
Mr Trump’s electoral vote count currently stands at 312 over Ms Harris’ 226 - which is 42 more than he needed to secure the White House for a second term.
The Republicans have also regained control of the Senate and look likely to retain a majority in the House of Representatives.
The latest good news for Mr Trump came as the White House confirmed Mr Biden would meet with the president-elect at the White House on Wednesday.
This type of meeting between the outgoing and incoming presidents is considered customary, but Mr Trump did not invite Mr Biden for one after making unsubstantiated election fraud claims that culminated in the January 6, 2021 Capitol riot.
Mr Trump also broke with precedent by skipping Mr Biden’s inauguration, but the White House has said Mr Biden will attend the upcoming ceremony.
