Washington, February 13 (RHC)-- U.S. President Donald Trump’s mental health is a source of great concern for some lawmakers on Capitol Hill, according to Al Franken, a Minnesota Democratic senator.  Franken made the comments on CNN’s “State of the Union” released on Sunday. 

Asked by the program's host if it is “true that Republican colleagues of yours express concerns about President Trump’s mental health,” Franken replied: “A few… There’s not a majority of them.” 

Senator Franken, who is a possible Democratic candidate for the U.S. 2020 presidential elections further outlined some of the “lies” that could prompt others to think so.  “We all have this suspicion that, you know, he lies a lot.  He says things that aren’t true.  That’s the same as lying, I guess," Franken said. 

“You know, 3 [million] to 5 million people voted illegally," added the Democratic senator, referring to Trump's claims that he lost the popular vote against Hillary Clinton because of widespread voter fraud.  Trump's critics have on several occasions called for evidence of such fraud but to no avail.  "That is not the norm for a president of the United States or actually for a human being," Franken noted.  

This is not the first time the U.S. president’s mental health is brought up in the country’s new political environment.  Mika Brzezinski, an American author, journalist and television host, suggested four months ahead of the 2016 presidential election that the Republican nominee is not mentally fit to serve as the commander-in-chief.   “Let’s stop pretending we’re dealing with someone who we can completely understand,” she said. 

Psychologists have also begun questioning Trump’s state of mind because of the type of temperament and behavior he has displayed in public appearances.
