President Donald Trump's former personal attorney Michael Cohen apologized to the Senate Intelligence Committee on Tuesday for lies he told during his 2017 testimony, CNN reports. “There is a reason that is a closed hearing, but he did spend quite a bit of time explaining what he had told us before that wasn't truthful,” Sen. Roy Blunt (R-MO) told reporters. Sen. Susan Collins (R-ME) also told reporters that Cohen seemed like “a very different guy” from the last time he appeared. “I'm really not permitted to talk about what happened this morning. I will say he has been asked many, many questions,” Collins said. “I've submitted some that have been asked and a couple that still haven't been. And it's an extensive grilling. But I really can't go into the specifics.” Cohen is expected to publicly testify on Wednesday, where he will reportedly disclose Trump's alleged role in crimes while he was in office. Cohen was sentenced to three years in prison for lying to Congress, among other charges.
