WASHINGTON (AP) — President Donald Trump staunchly defended his embattled Supreme Court nominee against a new allegation of sexual misconduct Monday, calling the accusations against Judge Brett Kavanaugh "totally political."

The president spoke a day after a second allegation emerged against Kavanaugh, a development that further imperiled his nomination to the Supreme Court, forced the White House and Senate Republicans onto the defensive and fueled calls from Democrats to postpone further action on his confirmation.

Trump, at the United Nations for his second General Assembly meeting, called the allegations unfair and unsubstantiated, made by accusers who come "out of the woodwork." He also questioned the political motivations of the attorneys representing the women, saying "you should look into the lawyers doing the representation."

On Kavanaugh, Trump stressed: "I am with him all the way."

The new accusation landed late Sunday in a report from The New Yorker, just a few hours after negotiators had reached an agreement to hold an extraordinary public hearing Thursday for Kavanaugh and Christine Blasey Ford, who accuses him of sexually assaulting her at a party when they were teenagers. Kavanaugh denies the accusation.

Presidential counselor Kellyanne Conway told CBS on Monday that the accusations against Kavanaugh sound like "a vast left-wing conspiracy," using rhetoric that echoed Hillary Clinton's 1998 description of allegations that her husband, President Bill Clinton, had had affairs.
