Theres no question that its going to be a challenge to get this implemented in such a quick time frame. The recommendation has been that 11 states implement this process within four weeks. And new york is one of those states. And for the rest of the country, within 12 weeks. Its going to require resources and planning and funding. And yet again, one more reason for congress to really take action when they come back into session, making sure that we have the resources funding we need to implement this on a widescale basis.

Dean reynolds is following the Trump Campaign in las vegas. U. S. A. reporter donald trump handily won nevada caucuses earlier this year back when his stand on illegal immigration was simple mass deportation and a big, new wall. We won with young. We won with old. We won with highly educated. We won with poorly educated. I love the poorly educated. Reporter but now, in the heat of the general election, trump is sounding like a candidate trying to broaden his support by smooth over the rougher edges of policy, such as immigration. There certainly can be a softening because were not throok hurt people. Reporter this afternoon, trump met with hispanic Business Owners in las vegas. Weve been doing very, very well with the latinos. We have been doing amazing. Reporter in nevada, the cbs news Battleground Tracker has Hillary Clinton ahead with hispanics who make up 20 of voters in the state preferring her by a wide markin.

Our National Poll last month found 40 of registered Republican Voters believe the undocumented should be forced to leave, but 60 of all voters thought they should be allowed to stay and apply for citizenship. Republican strategist and cbs news contributor Leslie Sanchez says trump has to be careful with his core supporters but practical. Trump is starting to realize that. Hes not going to win a general Election Campaign unless he talks about an approach that is compassionate and realistic. So as much as the cry will continue to be vocal and loud, its not going to change the political reality and the calculus as he tries to win in november. Reporter and as for Hillary Clinton, james, after a week of attacking Donald Trumps character and temperament and days of enduring his charge that she is a bigot, she stayed out of the public eye today.

One lawmaker is calling for an intervention for the governor after he unloaded on a political rival. Jim axelrod is following this. 95 of this state is white.

Reporter the twoterm republican governor exploded after a reporter told lepage that Democratic State rep drew gattine had criticized him for saying wednesday 90 of drug dealers arrested in maine are, black and hispanic people from out of state, a figure he cites using his own personal collection of headlines culled from newspapers. No, i did not call governor lepage a racist. Reporter gattine says he called those remarks racially charged but never called the governor a racist. I was really glad i wasnt in the room with him when he left it because he really sounded like somebody who was, you know, about to commit physical violence and it was really a stunning message. Reporter this afternoon, lepage apologized for the people of maine having to hear the voice mail but not for the voice mail itself. Everything i said to him is less insulting to me than being called a racist. Reporter after leaving the voice mail, lepage then said he wanted to challenge gattine to a duel and point his gun, right between his eyes. Today, j. B. , the governor backed off that saying it was simply a metaphor and that he meant no physical harm. Brown jim axelrod.

I took warfarin for over 15 years until i learned more about oncedaily xarelto. A latest generation blood thinner. Then i made the switch.
