White House warns that not all results will be announced immediately

"We may not know all the winners for a few days," said Press Secretary Karine Jean-Pierre.

The winning candidates in the midterm elections will not be known immediately. With less than 24 hours to go before the vote, White House Press Secretary Karine Jean-Pierre said it could take a few days to get the results:

We may not know all the winners of elections for a few days. It takes time to count all legitimate ballots in a legal and orderly manner.

The United States does not have a federal authority in charge of counting votes, it is the Secretaries of State who are responsible to oversee this process. Jean-Pierre warned that we will have to wait to find out the congressional results and the winners of the state and local elections.

Election results are usually announced shortly after the ballots are counted on the day of voting. The Oval Office Press Secretary claimed that the delay is due to the different ways in which Americans vote:

In modern elections more and more ballots are cast in early voting and also by mail. We’re in a different time … we’re just trying to communicate with the American people, let them know this process certainly has changed again in modern elections.

At this time, it is not known whether Joe Biden will hold a press conference after the midterms, as every president since Bill Clinton has done. "He’ll have a robust, pretty heavy schedule tomorrow here at the White House," Jean-Pierre said.
