The Republican candidate for the White House Marco Rubio expressed his outrage because his rival Donald Trump refuses to condemn the support of the Ku Klux Klan (KKK) ex-leader of his campaign, which, in his opinion, makes Trump "unelectable" as president.

"We cannot be a party who refuses to condemn white supremacists and the Ku Klux Klan. Not only is that wrong, it makes him unelectable," said Rubio Sunday in front of 2,000 people during a rally at the Patrick Henry College in Purcellville, Virginia, USA.

Rubio criticized the fact that Trump avoids condemning the support from former KKK leader David Duke after the CNN reporter Jake Tapper asked him on three occasions if he refuses the endorsement.

Hours later, Trump wrote a message on his Twitter account that Rubio failed to convince his critics.

"As I stated at the press conference on Friday regarding David Duke - I disavow," as can be seen on his personal Twitter account.

In the interview with CNN, Trump argued that he did not know about David Duke or white supremacists. He also refused to condemn any, on all three occasions that the journalist gave him opportunity to do so.

Senator Marco Rubio rejected in his rally that Trump does not know what the Ku Klux Klan is and recalled a statement made by the magnate in 2000, when he distanced himself from the idea of competing for the Reform Party nomination as David Duke was in the party.

It was one of numerous attacks from Rubio on Trump during the first of his four rallies today in Virginia, one of the twelve states and one territory where the primaries 'Super Tuesday' will be held on March 2.
