A top law firm and property services company have become the latest companies to sever ties with the Trump Organization following the January 6 riot at the U.S. Capitol. Seyfarth Shaw, a national law firm headquartered in Chicago, and Cushman & Wakefield, a global commercial real estate services firm, both said on Wednesday they would cease doing business with President Donald Trump's company. 'The firm has notified the Trump Organization that we will no longer serve as counsel,' Seyfarth spokesman Martin Grego told Bloomberg.
