Democrats captured both chambers of Congress in last Tuesday's midterms that dealt historic losses for Trump's Republican Party in states they had dominated for decades.

"America took a giant step back in History with the results of the last Election," Trump said in a post on Truth Social, saying that the stock market that had grown during his tenture took a loss after the vote.
