President Biden cast his early ballot in Delaware on Monday and told reporters he was confident Vice President Kamala Harris would defeat former President Donald Trump. He called Trump’s rally at Madison Square Garden in New York City on Sunday a disgrace.

Biden waited in line with other voters outside the Delaware Department of Elections and helped push an elderly woman in a wheelchair in front of him before casting his ballot. After voting, Biden greeted reporters outside, where he was asked if it was a bittersweet moment.

Biden responded: “No, this is just sweet.”

Biden stepped down from his re-election campaign in July after poor debate performances that fueled concerns about his health and Democrats’ worries about his chances of beating Trump.

Biden was asked what he thought of the huge rally Trump held at Madison Square Garden the night before.

“It’s beneath any president, but we’re used to that,” Biden said. “That’s why these elections are so important.”

Biden added that Trump questions his own character “every time he opens his mouth.”

Trump took the stage Sunday night before a packed house of thousands of supporters, focusing his speech on spiraling immigration, inflation concerns and looking to the future with lower consumer costs and securing the border.

When asked about the war between Israel and Hamas and a possible ceasefire, Biden responded: “We need a ceasefire, we need to end this war.”

Regarding another conflict abroad, the war between Russia and Ukraine, Biden was asked whether North Korea was deploying troops to help Russian President Vladimir Putin.

“It’s very dangerous,” Biden said of the apparent escalation.

The series of questions included asking whether he thought Elon Musk’s $1 million offer to swing-state voters who sign his political action committee’s petition in support of the Constitution was election interference. Biden called the tech billionaire’s offer “totally inappropriate.”
