ATTN:'s Matthew Segal sits down with Sen. Elizabeth Warren (D-Mass.) to discuss President Donald Trump's complicated relationship with Wall Street and the future of financial regulation. Notably, Warren calls out Trump for his claims of draining the swamp, telling Segal, "Are you kidding me? Here's a guy who said, 'I will drain the swamp ...I will get rid of those Wall Street guys.' ... And then he brings in, who? The Goldman Sachs bankers!" And that's just the beginning, watch Warren break it all down in the latest installment of "Paying Attention."
