>> on day one, i am going to begin swiftly removing criminal illegal immigrants from this country. >> he is not talking about a deportation force, but he is talking about being fair and humane. >> reporter: trump appears to be backing away from some of the harshest measures he proposed during the primaries. >> you're going to have a deportation force. and you're going to do it humanely. >> you cannot deport 11 million people. >> reporter: heated questions over that part of the plan led trump to eject univision's jorge ramos from a press conference last year. >> no, no, no. i'm a reporter and i have -- don't touch me, sir. don't touch me, sir. >> reporter: today, governor chris christie insisted there's no flip-flop. >> this is a guy who's been very consistent on no amnesty, no legalization, for folks who have been coming to the country illegally. >> reporter: but trump supporters do see a difference. what do you make of the change in tone that we've heard this week on the immigration issue? >> i think it's very positive. jeb bush had the same tone, i was a very strong jeb bush supporter. mr. trump is now coming around

to that position and i applaud him for that. >> reporter: do you think he's going to win votes with this new approach or lose them? >> probably win votes. >> i would agree. i would agree. >> reporter: the tricky part for trump could be selling a policy change to hardliners. last week he cancelled what was billed to be a major speech on the immigration issue. cecilia? >> david, thank you. next to some severe weather hitting parts of the country. in north dakota, video capturing one of two reported tornadoes. some residents were also pelted with tennis ball-sized hail. in the tropics, we're also tracking the first bands of a slow-moving storm. hitting the florida keys, heavy rain and flooding in some neighborhoods, and much more to come. i want to bring in rob marciano. where is this headed next? >> we've been watching this all week. the rains heading for florida. and they're spinning north of cuba. that's our newest tropical depression. also rains around houston. we expect this to get into the gulf of mexico.

year, and reduce his felony charge if he went to counseling so he could play. >> a felony conviction would have automatically disqualified him from attending the university of hawaii and obviously compromised his entire future. >> reporter: gunderson didn't have to check in with a probation officer. >> that was highly unusual and probably improper for this judge. >> reporter: court documents show gunderson ended up dropping out of school and quit counseling. since then, at least one more arrest for misdemeanor assault. judge persky not commenting tonight. but he's decided to only handle civil cases now. critics say that's not enough. >> we're going to have to go forward with the recall in order to ensure that he is no longer a judge. >> reporter: as for gunderson, he did end up serving jail time for beating his ex-girlfriend. he's due in court this week on that other arrest. meanwhile, brock turner is expected to be released from jail friday, after serving half of his six-month sentence. cecilia? >> lauren, thank you. we want to turn to a call for help that ended with a
