(AP) - Republican Donald Trump has picked up the endorsement of Alabama Sen. Jeff Sessions, as the presidential candidates get ready for Super Tuesday.
But Trump's rivals from both parties have been criticizing him for refusing to denounce an endorsement from Ku Klux Klan leader David Duke.
Republican Ted Cruz says it's "unfortunate" that Trump won't condemn Duke, and he says Duke has been making robo-calls urging people, "Don't vote for the Cubans in the race," referring to Cruz and fellow Republican Marco Rubio.
