Fact checking Trump's debate claims on immigration

>>> 40 PAST THE HOUR. NEW REACTIONS THIS MORNING AFTER DONALD TRUMP MADE A SERIES OF STATEMENTS ABOUT IMMIGRANTS IN LAST NIGHT'S DEBATE, INCLUDING A BASELESS CLAIM THAT MIGRANTS IN OHIO ARE EATING PEOPLE'S PETS. >> IN SPRINGFIELD THEY'RE EATING THE DOGS, THE PEOPLE THAT CAME IN, THEY'RE EATING THE CATS. THEY'RE EATING THE PETS OF THE PEOPLE THAT LIVE THERE. WHEN YOU LOOK AT WHAT SHE'S DONE TO OUR COUNTRY AND WHEN YOU LOOK AT THESE MILLIONS AND MILLIONS OF PEOPLE THAT ARE POURING INTO OUR COUNTRY MONTHLY WHERE IT'S, I BELIEVE, 21 MILLION PEOPLE, NOT THE 15 THAT PEOPLE SAY, THEY ALLOWED TERRORISTS, THEY ALLOWED COMMON STREET CRIMINALS. CRIME IN THIS COUNTRY IS THROUGH THE ROOF, AND WE HAVE A NEW FORM OF CRIME. IT'S CALLED MIGRANT CRIME. THEY HAVE DESTROYED THE FABRIC OF OUR COUNTRY. MILLIONS OF PEOPLE LET IN. A LOT OF THESE ILLEGAL IMMIGRANTS COMING IN, THEY'RE TRYING TO GET THEM TO VOTE. >> JOINING US NOW IS NBC'S HOMELAND SECURITY CORRESPONDENT JULIA AINSLEY. JULIA, IT'S KIND OF DIFFICULT WHAT ALL OF THESE STATEMENTS, YOU KNOW, DOGS, AND CATS AND PARAKEETS AND WHATEVER, LET'S TALK ABOUT WHAT THE FORMER PRESIDENT CONSISTENTLY SAYS, WHICH IS THAT, YOU KNOW, IMMIGRANTS ARE THE SOURCE OF CRIME, YOU KNOW, IT'S A TERM, MIGRANT CRIME. CAN YOU KIND OF HELP US THROUGH THIS? >> YEAH, I MEAN, IT'S A THING OF WHERE DO WE BEGIN. I'M HAPPY TO UNPACK ALL OF THAT. WE CAN TALK ABOUT SPRINGFIELD AS WELL. WHEN HE'S TALKING ABOUT THE MIGRANTS COMING IN, HE'S SAYING LIKE 20 MILLION MIGRANTS HAVE COME IN. THAT'S FALSE. WHEN YOU LOOK AT THE DATA EVERY MONTH, THE CUSTOMS AND BORDER PROTECTION, PUBLISHING THE STATS THROUGH THE BUSH ADMINISTRATION, THEY SAY THAT ABOUT 10 MILLION UNDOCUMENTED MIGRANTS HAVE COME IN THROUGH THE NORTHERN AND SOUTHERN BORDERS, AND INCLUDES PEOPLE WHO PRESENT THEMSELVES FOR ASYLUM, AND THOSE THAT PRESENT THEMSELVES LEGALLY THROUGH A PORT OF ENTRY. 20 MILLION, IT'S UNCLEAR WHERE HE'S GETTING THAT AND WHY HE DECIDED TO DOUBLE THE NUMBER. >> LET'S GET INTO THE NUMBERS. SO 10 MILLION ARE THE ESTIMATED AMOUNT OF PEOPLE THAT HAVE COME IN JUST IN THE LAST THREE AND A HALF YEARS. AND THAT DOESN'T INCLUDE WHAT, YOU KNOW, THEY CALL THE GET AWAYS, RIGHT, THE FOLKS THAT HAVE SIMPLY COME IN, AND WE DON'T KNOW HOW MANY. >> SURE. YEAH, AND IT'S HARD TO COUNT PEOPLE WHO YOU DON'T SEE OBVIOUSLY, AND IT COULD BE THAT THERE ARE MORE PEOPLE WHO ARE EVADING APPREHENSION, ESPECIALLY UNDER THE NEW ASYLUM LAWS. I FAIL TO GET INTO THE QUESTION YOU ASKED ME ABOUT CRIME. AS WE LOOKED ACROSS THE COUNTRY. FBI CRIME STATS SAY CRIME HAS COME DOWNDRAMATICALLY OVER THE LAST YEAR. SOME CITIES ARE NOT INCLUDED IN THE FBI CHECK LIKE NEW YORK. THAT IS ALSO A CITY THAT HAS REPORTED LOCALLY THAT THEY HAVE HAD A DROP IN CRIME. I WILL SAY WHEN WE TALK ABOUT MIGRANT CRIME, EVEN THOUGH OVERALL CRIME IN THE COUNTRY IS DOWN, AND WE KNOW THAT U.S. CITIZENS COMMIT MORE CRIMES PER CAPITA, THAN UNDOCUMENTED MIGRANTS. THERE ARE AREAS OF CONCERN. FROM VENEZUELA THAT HAS SPREAD INTO THE UNITED STATES COMMITTING CRIMES IN NEW YORK AND DENVER AND ELSEWHERE WHERE THERE HAVE BEEN LARGE VENEZUELAN POPULATIONS, OVER 100 OPEN INVESTIGATIONS BY HOMELAND SECURITY INVESTIGATIONS INTO THAT GANG. THERE'S ALSO BEEN A NUMBER OF ARRESTS FROM PEOPLE WHO THEY BELIEVE MAY HAVE TERRORISM CONNECTIONS. ALL OF THAT IS BEING PUT THROUGH THE JUSTICE SYSTEM. PEOPLE ARE BEING ARRESTED AND DEPORTED. WE DO NEED TO TALK ABOUT THAT AND NOT SAY THERE'S NO MIGRANT CRIME. OF COURSE THESE THINGS HAPPEN. IT'S A MATTER OF LOOKING AT THE DATA, AND WHEN TRUMP SAYS IT'S AT A LEVEL NEVER SEEN BEFORE, THAT IS FALSE. >> SO WHAT ABOUT THE WHOLE DOG STORY? >> WE'VE GOT TO GET INTO THAT OF COURSE. FIRST OF ALL, I HAVEN'T HEARD ANY REPORTS OF DOGS. THAT WAS THE FIRST TIME I HEARD ABOUT THAT LAST NIGHT. IN SPRINGFIELD, OHIO, THERE HAS BEEN A LARGE INFLUX OF HAITIAN MIGRANTS, AND A LOT OF PEOPLE SAID THEY SAVED THE TOWN. THEY WERE ANYONE TO COME IN AND DO A LOT OF JOBS. THEY NEEDED DEMAND FOR MORE HOUSING THAT COMES. AT A CITY COUNCIL MEETING, SOMEONE STOOD UP AND SAID THEY SAW A MAN EATING A DUCK IN THE PARK. THE CITY MANAGER SAYS THEY HAVE NO EVIDENCE TO BACK THAT UP. THERE'S ANOTHER VIDEO THAT'S CIRCULATED. I JUST GOT OFF THE PHONE WITH A HAITIAN BRIDGE ALLIANCE THERE, THE LARGEST ADVOCATES FOR HAITIAN IMMIGRANTS IN THE UNITED STATES. THEY SAY A LOT OF THIS STARTED ABOUT THE CAT, A VIDEO OF AN AFRICAN-AMERICAN WOMAN, NOT A HAITIAN MIGRANT IN SPRINGFIELD THAT WAS HAVING A MENTAL HEALTH BREAK, EATING A CAT. I CAN'T BELIEVE WHAT I'M SAYING HERE, BUT NONE OF THAT IS TIED TO THE HAITIAN MIGRANTS, AND SHE SAYS IT'S DEHUMANIZING TO TALK ABOUT THIS HAVING TO DO WITH HAITIAN MIGRANTS, AND IT'S ONE MORE THING THAT THIS COMMUNITY HAS TO DEAL WITH AS THEY TRY TO BOOST THE ECONOMY OF THE TOWN. >> JULIA AINSLEY, THANK YOU VERY MUCH. AND JUST ON A PERSONAL NOTE, IF YOU EVER WANT TO SEE A HARD WORKING, HONEST, EXTRAORDINARILY BENEFICIAL GROUP
