WEATHER ANYWHERE IN THE COUNTRY. GUYS, IT'S ALL YOURS. >> ALL RIGHT, LONNIE. THANK YOU SO MUCH. >>> ALL RIGHT, SWITCHING GEARS HERE. OUT WITH THE OLD AND IN WITH THE NEW AS OF 5:00 P.M., JUST SEVEN MINUTES AGO, TOM DONLON IS THE POLICE COMMISSION FOR THE NYPD AS A FEDERAL CORRUPTION PROBE CONTINUES TO SWIRL AROUND THE AGENCY. >> MARCIA KRAMER HAS BEEN ON TOP OF THE INVESTIGATION IN THE FALL. SHE'S HERE WITH THE VERY LATEST. MARCIA? >> Reporter: THE FEDERAL INVESTIGATION HAS CLAIMED ANOTHER VICTIM. THE MAYOR'S OFFICE, THEY HAVE BEEN FIRED AFTER REPORTEDLY TO HELP CONDUCT THE BROOKLYN BAR OWNER WHO HAD TROUBLE WITH POLICE OF THE BROTHER OF THE NOW FORMER POLICE COMMISSIONER, EDWARD CABAN. THE OWNER OF THIS CONEY ISLAND BAR, THE ONE WITH THE SECURITY GATES DOWN, IS THE REASON WHY CITY HALL SUDDENLY FIRED A COMMUNITY AFFAIRS AID TO MAYOR ADAMS, WHO PREVIOUSLY WORKED IN THE ENTERTAINMENT AND NIGHT LIFE UNIT. THEY HAD SAY RAY MARTIN WAS FIRED AFTER THE BAR OWNER CLAIMED MARTIN SUGGESTED HE CALL THE POLICE COMMISSIONER'S TWIN BROTHER, JAMES CABAN, IF HE NEEDED HELP IN STOPPING POLICE ENFORCING NOISE COMPLAINTS. JAMES CABAN WANTED $2,500 PAY UPFRONT. WE INVESTIGATED THE COMPLAINTS, FIRED HIM THE SAME DAY, SAID A SPOKESPERSON FOR THE MAYOR. BUT JAMES CABAN'S LAWYER INSISTED THEIR CLIENT HAD DONE NOTHING WRONG. MR. CABAN UNEQUIVOCALLY DENIES ANY WRONG DOING. HIS WORK AS A CONSULTANT AND ACTING AS A LIAISON BETWEEN A DEPARTMENT AND A PRIVATE COMPANY IS PERFECTLY LEGAL. THIS IS EDWARD CABAN'S RESIGNATION AS POLICE COMMISSIONER, OFFICIALLY TOOK EFFECT AND INTERIM POLICE COMMISSIONER, THOMAS DONLON TOOK THE OATH OF OFFICE. CABAN WAS ONE OF THE MAYOR'S INNER CIRCLE SUBJECTED TO RAIDS. AND SHEILA AND CBS NEWS NEW YORK'S POLITICAL TALK SHOW, THE POINT, DAVID BANKS SAID HE HAD DONE NOTHING WRONG AND IS COOPERATING WITH THE INVESTIGATION. IF A STUDENT OR A TEACHER WERE TO COME UP TO YOU AND ASK YOU WHAT'S GOING ON, WHAT WOULD YOUR ANSWER BE TO THEM? >> I THINK WHAT I WOULD SAY TO THEM IS THAT IN LIFE, YOU MAY HAVE CHALLENGES, BUT ALWAYS HOLD YOUR HEAD HIGH. LIVE YOUR LIFE AND WALK WITH INTEGRITY. I'VE ALWAYS DONE THAT, AND I WOULD ENCOURAGE ALL OF OUR KIDS, ALL OF OUR TEACHERS, AND ANYONE ELSE TO DO THE SAME. >> Reporter: NOW IN CASE YOU'RE WONDERING, TOM DONLON IS BEING CALLED THE INTERIM POLICE COMMISSIONER. BECAUSE THINGS HAPPENED SO FAST, MAYOR ADAMS DIDN'T HAVE TIME TO DO A NATIONAL SEARCH FOR A NEW TOP COP. NOW HE MIGHT GET THE JOB PERMANENTLY, BUT HE WAS PICKED BECAUSE HE HAS IMPECCABLE LAW ENFORCEMENT CREDENTIALS BECAUSE THE MAYOR KNEW HIM WHEN DONLON WAS THE STATE'S DIRECTOR OF HOMELAND SECURITY, AND ADAMS WAS THE STATE SENATOR, GUYS? >> SO MUCH MORE TO COME HERE. THANK YOU. >> WE KNOW YOU'LL STAY ON TOP OF THIS FOR US. >>> FROM THE ONGOING INVESTIGATION AND INTO CITY LEADERS, DO STAY WITH CBS
