republican lawmakers declare war on major-league baseball, after baseball moves the all-star game from atlanta over new voting restrictions. that is just ahead but we begin with important testimony in the trial of fired police officer derek chauvin. taking the stand today, the doctor, who tried but could not save george floyd's life. and the police chief that told jurors what chauvin did to floyd went against department policy, training, ethics, and values. cnn's omar jimenez joins -- joins us, with our coverage. . >> reporter: the start of week two of testimony, and the current-minneapolis police chief takes the stand in the trial of derek chauvin, his former officer. >> do you believe have a belief, as to when this restraint, restraint on the ground, that you viewed, should have stopped? >> once mr. floyd had stopped resisting. and certainly, once he was in distress and trying to verbalize that. to continue to apply that level of force to a person, prone out, handcuffed behind their back. that -- that -- that, in no way, shape, or form, is anything that is by policy. it is not part of our tr

a month ago, we were watching the horrible images come in from two-mass shootings in and around atlanta. seems a long time ago, doesn't it? the sad fact is, though, that mass shootings have become so common, it may, soon, be hard for one not to fall on the anniversary of another. this is a map of mass shootings in just the last month, which we're defining as four or more people shot, wounded, or killed, excluding the gunman. one other thing to note. there is only room on the map to show a little less than half. the full count, again, over just a single month since the atlanta shootings is 45 and the map is profound as it might be, doesn't do justice to the story. doesn't capture the horror. it doesn't capture the wounds, and the deaths of so many americans. the map doesn't tell the story of the five people, who were shot and wounded on march 17th in stockton, california. or the four shot in oregon, a day later. in houston, on the 20th, five shot at a nightclub. that same day in dallas, eight people shot and one killed in philadelphia. that night someone opened fire at a party, kill one

he again assailed major league baseball for moving its all-star game out of atlanta in protest to the law, a move he said was, quote, irritating one hell of a lot of republican fans. he also made a reference to delta airlines and coca-cola, both headquartered in atlanta, both which have opposed the law. >> republicans buy stock and fly on planes and drink coca-cola, too. so what i'm saying here is i think this is quite stupid to jump in the middle of a highly controversial issue particularly when they have their facts wrong. >> keeping them honest, mcconnell hasn't always felt that way. back in 2012 in a speech to the american enterprise institute, he said that all corporations, quote shore, be free to express themselves on the issues of the day. again, quoting i mean who is afraid here? let's all have a conversation he said about the future of the country. meanwhile, the former president has weighed in, as well, in a statement over the weekend he called for a boycott of delta and coke among others but in a phone interview with a conservative cable news network newsmax, he directed so

in atlanta and colorado. with the attorney general by his side, he's going to go through the executive actions that they believe will help with some of the gun violence we've seen. one is a rule to stop the proliferation of the so-called ghost guns. kits that people can order and assemble in as little as 30 minutes. they don't have serial numbers, that's part of the concern. white house officials have with the ghost gun. and they want to increase the regulation of the braces that people can put on pistols. this is similar to the one that the shooter in colorado used. you can put it on a pistol and it makes it more accurate and stable, so you're able to hit your target more easily. so the thing is with these and with a few other things that they're going to be introducing tomorrow, they fall pretty short of the sweeping measures that president biden promised on the campaign trail. but when the white house was asked about that, what exactly these measures will look like, how they'll stop what president biden sa

, two police officers were shot and wounded earlier this morning, during a high-speed chase west of atlanta. all of this, of course, is happening with the twin cities, already, on edge, as the prosecution continues to make its case against a former-minneapolis police officer, in the killing of george floyd. president biden spoke to the moment, and the mood, this afternoon. >> are you concerned things could be on a razor's edge, sir? >> i'm not going to speculate, now. i'm -- i'm hopeful that there'll be a -- a verdict and an outcome, that will be supported by the vast majority of the people in the region. and that's my expectation. >> shortly before airtime, the president tweeted this message. quote, today i am thinking about daunte wright and his family. and the pain, anger, and trauma that black-america experiences every day. while we await a full investigation, we know what we need to do to move forward. rebuild trust to ensure accountability, so no one is above the law. cnn's adrienne broaddus is in brooklyn center, minnesota, for us tonight. so, adrienne, daunte wright's death was rule

since atlanta spa killings on march 15, there have been 50 mass shootings in the united states according to analysis according to the gun violence, a kif, local media and police reports. you've long pushed for gun control legislation. we spoke in mid-march. you said because you've failed in the past, that doesn't mean one should not continue and try to if it for change. do you still have optimism tonight? >> i do. listen, the voters did their part. they put in charge of congress majorities that support universal background checks. they put a president in the white house who wants to sign that bill. now it's up to us to deliver. 2013 now, eight years ago, we lost a vote on background checks. and since then, we've been building up political power in the anti-gun violence movement. today we are stronger than the gun lobby. and i think that's part of the reason why i am having, i think, real substantive discussions with several republicans about how we can bring a bill to the senate floor in the next month or two that will dramatically expand the number of gun sales that have to be submitted

police departments in atlanta, chicago, and washington, also, taking precautions. testimony ended today in court. closing arguments will be heard, on monday. tension, as you can see from those images and as you might imagine, is running high. i have more now, from sara sidner. >> i will invoke my fifth-amendment privilege today. >> reporter: for the first time since the start of the trial, former-minneapolis police officer, derek chauvin. he chose not to take the stand as a witness in his own defense, leading the defense to rest its case. >> your honor, at this time, the defense rests. >> reporter: the prosecution then brought back its star-medical witness to refute the idea, brought up by yesterday's defense expert. >> it is an extremely toxic gas. >> reporter: that exhaust from the squad car's tailpipe, possibly, led to carbon-monoxide poisoning of george floyd. >> do you agree with that proposition, that's highlighted there? >> no, i do not. it's simply wrong. >> reporter: just before that, the prosecution attempted to introduce new-lab result evidence about car
