Reporter as dozens of impeachment protests are hold across the country sunday, the white house denies the president is distracted and it working on getting the stalled Gop Health Care bill passed.

These marchers had as they walked toward the Fishermans Wharf chanting antipresident trump slogans and carrying signs calling for his impeachment. The tweet the final straw for some. For others the thing that will keep them energized until he is really out of the white house. To just go after the media which is the pillar of our democracy just because they disagree with what youre saying is fundamentally one of the breaking points. Its appalling.

One of the most valuable pieces of undeveloped land in San Francisco is still a hot spot for controversy. For four years, our investigate of unit has exposed allegations of misconduct at the Hunters Point shipyard. The developments have been very interesting. Former workers involved in the cleanup of the site are warning of a radioactive coverup. They want the company at the center of it to pay the price. Investigative reporter liz wagner has the details of a new move to stop the company from winning future government contracts. Reporter this petition filed today asks federal regulators to revoke the republicans license contractor hired to clean up radiation at the shipyard. In this petition, seven former workers detail ways they say the company cheated on the billiondollar cleanup. This filing paints the most comprehensive picture to date of alleged misconduct at Hunters Point. Since 2006, virtually every step of the radioactive cleanup at Hunters Point was a fraud. Reporter the message coming from critics thursday was clear. The government needs to stop tetra tech from performing any more radiation cleanup. The Community Group greenaction filed this petition with the Nuclear Regulatory commission detailing what whistleblowers call intentional fraud by the company. That why were here today. Reporter former workers came together to say for years tetra tech downplayed the extent of radiation on the shipyard which is slated for parks and condos. The company cut corners to make more money. In these declarations they contend radioactive soil likely ended up back in the ground without ever being kleened up and contaminated soil was being shipped across the state under the guise it was clean. Reporter art jar controlled the trucks that came in to Hunters Point and saw what left. You have confidence that the soil that was leaving Hunters Point was actually clean . I have confidence that it very often wasnt. Reporter jar and other workers say employees tampered with Radiation Detection equipment and changed test results. The activity was often directed by supervisors, even toplevel managers. It was falsified. The whole process was a farce. Reporter Compliance Officer bert baurs points to a process where soil was scanned for radiation. He and others say the woman in charge either through incompetence or intentional fraud made it look like the soil was clean when it may not have been. Bauers says a lot of that soil was put back into the shipyard where it remains today. Were talking about contaminants on that site that present a significant hazard. The happenhazard way that it was handled. Reporter bauers and others spoke with nbc bay area starting in 2014 warning of a botched cleanup. Tetra tech was caught mishandling soil samples and falsifying data. The company says it cleaned up those problem areas and retrained workers. Its got to stop now. Reporter now, together, former workers say they want the public to know the full extent of the fraud they say happened at Hunters Point, and they want the feds to act quickly. The nrc has four months to respond to the petition. Meanwhile, following our series of reports, the navy is now investigating the companys past activities on the shipyard.
