A look at campaign activities on Sunday:

OBAMA

Obama praised Donnelly during a rally in northwest Indiana as someone who's honest and direct, telling voters, "You don't want a 'yes' man." Obama's appearance in Gary was sandwiched between Trump's trips to Indiana on Friday and Monday to help Braun.

Donnelly has often sounded far more like Trump than Obama on issues. He angered some Democrats by embracing some of Trump's priorities, including a border wall with Mexico. But he has supported the Affordable Care Act, the health care overhaul signed into law by Obama.

The former president told thousands of cheering supporters that he and Donnelly don't always agree. But he said it was more important to elect a senator who will put what's best for his state over his party.

TRUMP

Rallying his faithful in Macon, Georgia, Trump praised Kemp as a "strong man" and "strong personality" and said Kemp would become a great governor for Georgia.

The president assailed Kemp's Democratic opponent, Stacey Abrams, as "one of the most extreme far-left politicians in the entire country." The Georgia race has garnered attention from a list of high-profile backers, including Oprah Winfrey, who campaigned for Abrams last week. Abrams is attempting to become the nation's first black female governor.

Trump said Winfrey was a friend of his until he ran for president but he is now urging Georgia voters to listen to his endorsement instead of hers.

BLOOMBERG

Former New York Mayor Michael Bloomberg is pumping another $5 million in national advertising into the final two days before the midterm elections, urging voters to support Democrats because of his concern about "the direction of our nation."

Bloomberg, the billionaire independent who is considering a 2020 presidential campaign as a Democrat, appears in the 2-minute ad airing Sunday during CBS's "60 Minutes." It will also air Monday on cable and broadcast networks.

Bloomberg says in the ad that the nation needs to support Democrats to "send a signal to Republicans in Washington that they have failed to lead, failed to find solutions, and failed to bring us together."
