White House press secretary Sean Spicer said on Monday that President Trump stands by his claim that former President Obama is a “bad or evil guy, " reports ABC News.
During a press briefing, Spicer was asked about a recent CBS interview in which the president seemed to dodge questions about his previous negative descriptions of Obama.
Spicer said, “I think the point is he clearly stands by that. That’s something that he made very clear, if you look at the entire back-and-forth.” 
Trump ended his CBS interview with John Dickerson early after the journalist continued to press him about his wiretapping claims against Obama. 
The conversation began to turn when Dickerson asked the president if Obama had given him any helpful advice about the job. 
Trump said, “Well, he was very nice to me. But after that, we've had some difficulties. So it doesn't matter. You know, words are less important to me than deeds. And...you saw what happened with surveillance. And everybody saw what happened with surveillance…” 
After Dickerson brought up the fact that Trump had called Obama “sick and bad,” the president said, “Look, you can figure it out yourself. He was very nice to me with words, but-- and when I was with him -- but after that, there has been no relationship.” 
In March, Trump had tweeted, “How low has President Obama gone to tapp my phones during the very sacred election process. This is Nixon/Watergate. Bad (or sick) guy!” 
However, in regards to standing by this claim, Trump told Dickerson, in part, “I don't stand by anything...you can take it the way you want. I think our side's been proven very strongly. And everybody's talking about it. And frankly it should be discussed. I think that is a very big surveillance of our citizens...” 
Dickerson kept pressing the issue, and Trump eventually walked away from the interview, saying, “Okay, it's enough. Thank you. Thank you very much.” 
No evidence has been presented thus far to corroborate Trump’s wiretapping allegations.
