voters before the 2016 election. today prosecutors calling daniels' former lawyer, keith davidson, who helped broker the deal. he testified daniels' story had been floating around the internet for years, but trump's team made no effort to buy it until the final weeks of the 2016 campaign, after the "access hollywood" tape became public, trump boasting about groping women. >> when you're a star they let you do it. you can do anything. >> reporter: before >> reporter: davidson testifying, "before access hollywood tape, there was very little, if any, interest." but after, “that interest reached a crescendo.” davidson found himself negotiating directly with michael cohen. the two men struck a deal. daniels would get $130,000 for her story. davidson testified, "it was my understanding that mr. trump was the beneficiary of this contract." but the payment kept getting delayed. davidson saying cohen told him, “what do you expect me to do? my guy is in five states a day. i'm doing everything i can.” but davidson was convinced they were “trying to kick the can down the road until after the election." ultimately cohen told him "god damnit, i'll just do it myself”" and paid the porn star out of his own pocket. prosecutors say when trump later reimbursed cohen, he illegally falsified dox yooments to make it all look like a legal expense. trump almost egging on the judge today, calling him rigged, crooked, and conflicted, but the judge made clear if these violations of the gag order continue, he's not abouf throwing trump in jail. david? >> david: thank you, aaron.

monitor women's pregnancies to possibly prosecute women who violate abortion bans. tonight, president biden responding, and here's mary bruce. >> reporter: tonight, donald trump says he won't stand in the way if states want to monitor pregnant women to make sure they comply with abortion bans. and he won't step in to prevent states from prosecuting women who violate those bans by ending their pregnancies. in an interview with "time" magazine, trump was asked -- do you think states should monitor women's pregnancies so they can know if they've gotten an abortion after the ban? trump saying, "i think they might do that. again, you'll have to speak to the individual states." them p then asked if he'd be comfortable with states who pros kus women who get abortions. his response, "it'ser vel rant whether i'm comfortable or not. it's totally irrelevant, because the states are going to make those decisions." in the 2016 campaign, trump said women who have abortions should be punished. >> do you believe in punishment for abortion? yes or no as a principle? >> and the answer is that there has to be some form of punishment. >> for the woman? >> yeah. there has to be some form. >> reporter: he quickly backtracked. as president, he appointed three of the justices who overturned roe versus wade, something he continues to brag about. >> we broke roe v. wade, and we did something that nobody thought was possible. we gave it back to the states, and the states are working very brilliantly. >> reporter: president biden calling trump's comments today “reprehensible.” saying, “donald trump doesn't trust women. i do.” both biden and trump well aware abortion could be on the ballot in 13 states this november, including critical battlegrounds pennsylvania, nevada, arizona and florida. and that every time abortion has been on the ballot since roe was overturned, even in red states, abortion rights have won. the biden team is trying to seize on this issue, with the vice president taking on a stepped up role. she will be down in florida tomorrow, as the state's six-week abortion ban goes into effect. now, trump has said that ban is too severe, but he still won't say how he will vote on the issue when it's on the ballot in november. david? >> david: mary bruce live at the white house for us. thank you. we are learning more tonight after some terrifying moments, an suv crashing

so-called grandparent scam. stealing millions of dollars, in a multinational scheme. here's how it worked -- the scammer would call the senior citizen, claiming thousands of dollars were needed for a loved one who had been in a car accident involving a pregnant woman. the elderly person would panic, agreeing to pay the money. a courier would then show up at that person's home to collect the money, or the victim was instructed to mail the cash. >> they're susceptible. they're not as familiar with technology as younger people, and therefore, they're most likely to be impacted by this type of fraud. >> reporter: tonight, the fbi is encouraging financial institutions to do more to protect senior citizens if they notice their accounts being drained, david. >> david: pierre thomas, thank you.
