"I talked to Mayor Pete and Amy Klobuchar... I wished them all the best and I thought both of them behaved themselves... but they represented their country and their states very well, and I felt sorry for them and I am in it to win it," Bloomberg said.
Klobuchar, a U.S. Senator from Minnesota, will announce the suspension of her White House campaign in Dallas on Monday where she will publicly back Biden, a campaign aide said.
Former South Bend, Indiana Mayor Pete Buttigieg also plans to endorse Biden a day after ending his campaign, a top adviser said.
