Dallas Mayor Eric Johnson has defended the latest cost estimates to repair City Hall, stating he trusts the firms providing the estimates and no better alternative exists. Johnson also responded to criticism about his focus on City Hall and stated that he is fully engaged in the process. He accepted the latest City Hall repair estimates, including a $1 billion price tag over 20 years, despite calling the current building "not a great place to work" for employees. He also dismissed skepticism about the numbers, stating that the City Council recently authorized City Manager Kimberly Bizor Tolbert to explore all options before making a final decision. Johnson confirmed ongoing negotiations to keep the Dallas Mavericks and Dallas Stars in the city, but did not disclose details.
