From The New York Times:

President Trump said on Tuesday night that he was “absolutely willing” to accept the results of the midterm elections, and was prepared to work with Democrats. “We’ll, you know, look forward to working with them,” he said in a phone interview with The New York Times. “We’ll probably work something out.”
Mr. Trump blamed Republican losses on the fact that he was not on the ballot, and called his decision to go to war with Iran a “very wise decision.” He said he had no regrets about endorsing candidates such as Senator Darline Graham, Republican of South Carolina, and Ken Paxton, the Republican attorney general of Texas, who both lost their Senate bids.
