Many Republican senators claimed Joe Biden as the President-elect after he received 320 votes from the electoral college.

"In my opinion, that is how we determine the presidential elections in this country. It's our Constitution and I always abide by it," Republican Senator John Thune on Wednesday.

Thune said Democratic candidate Joe Biden became president "as soon as it crossed the 270 electoral votes".

Sen. Roy Blunt, a member of the Republican leadership, said it was a "constitutionally correct" process and that the electors voted to determine the president's election.

Roy Blunt, a member of the United States Congressional Commission on Inauguration (JCCIC), added he would work with President-elect Biden and his committee to plan the new president's inauguration.

When asked if Biden is the president-elect, Sen. Shelley Moore Capito, a Republican member of the group leading the Senate majority, admitted the Democratic candidate had won.

Senator Rob Portman, another member of the group leading the Senate majority, also declared that "the electoral college's vote clearly shows that Joe Biden is President elected".

However, many Republican senators still refuse to directly recognize the victory of the Democratic candidate Biden.

"I don't have to recognize anything, the Constitution does it. I abide by the Constitution," Republican Senator Chuck Grassley announced when reporters asked him if he would recognize Biden as President-elect.

Republican Senator John Cornyn believes Biden is president-elect "but has to wait for ongoing lawsuits" between now and January 20.

The Electoral College on December 14 (December 15, Hanoi) has completed the presidential election process, in which Joe Biden won 306 votes, President Donald Trump got 232 votes.

The electoral college's voting results are often symbolic and attract little attention, but this year has become important as President Trump decided not to lose.

On January 6, US Vice President and Senate President Mike Pence will preside over a plenary session of Congress to read aloud certificates of the electoral votes of each state, alphabetically.

A group of Republicans, led by Senator Mo Brooks, is planning to reverse the election by challenging the results of the electoral votes in parliament.
