I'm not going to get on my high horse and suggest Lewis is off limits for criticism, but the specific criticism Trump landed on is laughable and insulting to Lewis' career. Further, for a person trying to convince America he's going to be the President of all Americans and earn the trust of those who think he's a bad choice for minorities, he needs to have better ****ing sense than to attack a civil rights hero during a holiday weekend dedicated to the civil rights movement. I agree that he wasn't actively trying to offend anyone (beyond Lewis) or come across as racially insensitive, but at some level he still should be accountable for the stupid **** he spews out on Twitter.
