THAT SERVICES ARE LACKING. >>> AND GOOD EVENING, THANKS FOR JOINING US AT 6:00. BACK IN PUBLIC SINCE SPEAKING OUT ABOUT THE FBI RAID ON HER OWN HOME. THE METROPOLITAN TRANSPORTATION COMMISSION. THIS IS HAPPENING IN SAN FRANCISCO, WHERE THEY VOTED TO PUT A $20 BILLION BOND ON THE MEASURE ON THE NOVEMBER BALLOT TO BOOST AFFORDABLE HOUSING AROUND THE BAY AREA. BUT OUR CREW SAYS THAO LEFT WITHOUT HER BELONGINGS, WHICH HER AIDE HAD TO COME BACK TO GET. THAO REFUSED TO SPEAK TO THE MEDIA TODAY. SO THE FBI IS ALSO REMAINING TIGHT LIPPED NEARLY A WEEK AFTER THE RAID CONNECTED TO THE FAMILY AND THEIR RECYCLING COMPANY CALIFORNIA WASTE SOLUTIONS. THE IRS AND U.S. POSTAL INSPECTION SERVICE WERE ALSO INVOLVED IN ONE OF THE RAIDS. WHILE THE POSTAL INSPECTION SERVICE HAS DECLINED TO COMMENT, IT IS COMMON KNOWLEDGE THEY INVESTIGATE CRIMES LIKE MAIL FRAUD. NOW OUR DA LIN HAS UNCOVERED THE U.S. POSTAL SERVICE THAT IT OWES TENS OF MILLIONS OF DOLLARS AFTER DELIVERING CAMPAIGN MAILERS AIMED AT BENEFITING THAO WHEN SHE WAS RUNNING FOR MAYOR. >> Reporter: ELECTION YEARS BRING GOOD BUSINESS TO THIS MAIL AGENCY. BUT HE DOESN'T CARE MUCH ABOUT POLITICS. >> AND WE ARE HERE TO PROVIDE A SERVICE TO DO A GOOD JOB, REPUBLICANS, DEMOCRATS. WE DON'T SHOW ANY POLITICAL FAVORS. >> Reporter: OVER THE YEARS JOHNSON HAS PRINTED ALL KINDS OF POLITICAL ADS. THE GOOD, THE BAD, AND THE UGLY. BUT ONE PARTICULAR JOB ALMOST COST HIM HIS LIVELIHOOD. >> I'VE BEEN VERY HEARTBREAKING, VERY DISTURBING, VERY EMOTIONAL. >> Reporter: JOHNSON SAYS A COUPLE OF WEEKS BEFORE THE NOVEMBER 2022 GENERAL ELECTION, THIS MAN, MARIO JUAREZ, A LONG-TIME CUSTOMER CONTRACTED HIM TO PRINT ROUGHLY 170,000 ATTACK MAILERS TARGETING OAKLAND MAYORAL CANDIDATES IGNACIO AND LOREN TAYLOR. >> AND MY SKIN IS DARKENED, MY EYES HAVE TURNED RED. THE EYE BROWNS ARE POINTY IN THAT SORT OF INVOKING IMAGES OF A DEVIL OR SOMETHING LIKE THAT. >> Reporter: JOHNSON SAYS THE ATTACK ADS WENT OUT ABOUT ONE WEEK BEFORE THE ELECTION. HE SAYS JUAREZ PAID HIM ABOUT $31,000 FOR HIS SERVICE AND GAVE HIM THREE CHECKS TO PAY THE U.S. POSTAL SERVICE FOR THE POSTAGE. AFTER THE MAILERS WENT OUT, ALL THREE CHECKS BOUNCED, TOTALING MORE THAN $53,000. JOHNSON SAYS WITH INTEREST, JUAREZ NOW OWES THE U.S. GOVERNMENT ROUGHLY $60,000. >> THE USPS PUT A POSTAL STOP ON MY BUSINESS DIRECT MAIL PERMIT. >> Reporter: HE SAYS HIS PERMITS REMAIN SUSPENDED. THE MAILER SAYS IT IS FUNDED BY MARIO JUAREZ AND HAS INDEPENDENT EXPENDITURE OR I.E. ACCOUNT CALLED CALIFORNIA FORWARD NOW. WE CHECKED TO SEE WHO DONATED MONEY TO THE I.E. ACCOUNT, BUT IT DOESN'T APPEAR JUAREZ FILED ANY PAPERWORK TO IDENTIFY THE DONORS, REQUIRED BY CAMPAIGN FINANCING LAWS. >> BIRTHDAY PARTY. >> Reporter: WEST KNOWS WHO PAID FOR IT, SERVING AS THAO'S CHIEF OF STAFF WHEN THAO WAS THE DISTRICT FOR COUNCIL MEMBER. WEBB ALSO VOLUNTEERED ON THAO'S MAYORAL CAMPAIGN, BUT WEBB RESIGNED FROM THAO'S OFFICE AFTER THAO WON THE ELECTION, CITING CONCERNS OVER PUBLIC CORRUPTION. WE DID AN EXPENSIVE REPORT ON THE PAID TO PLAY ALLEGATIONS AGAINST THE MAYOR AND HER BOYFRIEND LAST WEEK. >> THE POST OFFICE IS INVOLVED WITH THIS INVESTIGATION BECAUSE IT WAS THE MAIL FRAUD WITH THEM USING THE FUNDING TO GET THOSE FLYERS SENT OUT. >> Reporter: WEBB SAYS ANDY DUANG WAS BACKING THAO FOR MAYOR. WEBB CLAIMS HE WAS PAYING JUAREZ TO ATTACK THE CHIEF RIVALS. SHE RECALLED ONE MEETING BETWEEN THAO, DUANG, AND JUAREZ AT A JACK LONDON SQUARE RESTAURANT. >> HE WAS LIKE YEAH, I NEED TO TALK TO YOU ABOUT SOMETHING. AND MARIO WAS LIKE YEAH, I NEED SOME MORE MONEY. THAT WAS HIS EXACT WORDS. AND HE AND SHE THINK AND SHENG AND MARIO STOOD RIGHT THERE AND SAID YEAH AND I WAS LIKE WHOA. I KNOW THEY'RE NOT SUPPOSE TO BE DOING THAT DURING THE CAMPAIGNS. THEY ARE NEVER SUPPOSE TO WORK TOGETHER. THEY ARE SUPPOSE TO BE TWO SEPARATE TOTAL ENTITIES. >> Reporter: WEBB AND JOHNSON BELIEVE THE UNPAID POSTAGE OR THE MAILERS COULD BE ONE REASON WHY THE U.S. POSTAL INSPECTION SERVICE WAS INVOLVED IN LAST WEEK'S RAID. >> I CAN'T SPEAK TO THE U.S. POSTAL SERVICE INVESTIGATION. BUT WHAT I CAN SAY IS TO STIFF SMALL BUSINESS BASED IN OAKLAND, A BLACK OWNED BUSINESS OUT OF $60,000 IS SHAMEFUL. >> Reporter: THEY DEFERRED ALL QUESTIONS TO THE FBI, WHICH HAS DECLINED TO COMMENT ON THE RAIDS. THE FBI INVESTIGATORS HAVE NOT ACCUSED THAO, JUAREZ OF ANY WRONG DOING. BUT THE ALAMEDA COUNTY DISTRICT ATTORNEY CHARGED HIM WITH ONE COUNT OF FELONY FOR PASSING BAD CHECKS. AS FOR JOHNSON, HE IS USED TO PRINTING MUD SLINGING ADS. HE'S NOT HAPPY HE'S CAUGHT UP IN ONE. >> IT IS ALSO AN EMBARRASSMENT TO MY BUSINESS TO BE INVOLVED IN THIS TYPE OF SITUATION. >> Reporter: MAYOR THAO'S SPOKESPERSON SAYS THEY WERE NOT ENGAGED WITH RUMOR. SHE SAYS THE MAYOR WILL SPEAK AT A LATER TIME. WE CONTACTED CALIFORNIA WASTE SOLUTIONS FOR A COMMENT FROM ANDY. WE ALSO CONTACTED MARIO JUAREZ. WE ARE STILL WAITING FOR THEIR RESPONSE. >> LOREN TAYLOR LOST THE 2022 MAYORAL ELECTION BY LESS THAN 700 VOTES TO SHENG THAO. TAYLOR IS PUTTING TOGETHER A TEAM TO RUN FOR THE MAYORAL SEAT IF THAO IS
