The st. Louis blues are the stanley cup champions. Brennan and victory for st. Louis, and laila. I finished my battle. They were my inspiration so i knew they were going to finish as well. Brennan good evening. Im margaret brennan. This is our western edition. Secretary of state mike pompeo could not have been more blunt. He said iran was behind the attacks on two tankers today in the gulf of oman in the middle east. One is in danger of sinking. The other may drift into iranian waters. Tensions were already running high after similar attacks last month. Tonight, the u. S. Military says it has no interest in engaging in a new conflict, but it is ready to defend u. S. Interests in the region which is the gateway for a third of the worlds crude oil. David martin begins our coverage. Reporter one tanker was hit by three explosions which u. S. Officials say were caused by mines planted by iran. The crew abandoned ship and the vessel burned furiously for hours, sending up a plume of smoke that could be seen from space. The other was hit by two explosions. Its crew abandoned ship when it realized there was still one unexploded mine attached to the hull. The u. S. Then watched and recorded an iranian patrol boat coming alongside and removing the unexploded mine from the tankers hull in effect, making off with the evidence. Thats one reason secretary of state pompeo laid the blame squarely on iran. It is the assessment of the United States government that the Islamic Republic of iran is responsible for the attacks that occurred in the gulf of oman today. Reporter the attacks came on the same day japans Prime Minister abe was in iran meeting with the Supreme Leader ayatollah khameni in an effort to ease tensions which have been building ever since the u. S. Dispatched an Aircraft Carrier and b52 bombers to the region in response to intelligence of imminent iranian attacks. The Supreme Leaders government then insulted japan by attacking a japanese owned oil tanker just outside of iranian waters, threatening the lives of the entire crew, creating a maritime emergency. Reporter the crew from one of the tankers was taken aboard a u. S. Navy warship. The 23 members of the other crew were taken aboard an Iranian Naval vessel and are still in iranian hands. One u. S. Official said its not clear if the crew was in fact rescued or is being detained as possible hostages against the threat of a u. S. Military attack. But, margaret, just a short time ago, the u. S. Central command, which controls operations in the persian gulf, put out the following statement we have no interest in engaging in a new conflict in the middle east. We will defend our interests, but a war with iran is not in our strategic interest, nor in the best interest of the international community. Margaret. Brennan david martin at the pentagon. Here with me is michael morrell, a former acting c. I. A. Director and cbs News Senior National security contributor. You just heard david martin describe what the pentagon says is not a fight theyre looking for. Diplomacy is the first foot forward. So how much risk is there of this becoming a military conflict . Margaret, i dont think the United States will respond militarily here because we were not attacked directly. And i think that would be predicate for the president to respond militarily. But i think the risk of conflict is growing, and i think its growing dangerously. And i think the way it could play out is that one of our allies, united arab emirates, or saudi arabia, would respond to this attack or another attack like it to deter the iranians, and that would escalate into a broader conflict that could draw us in. Brennan today, irans top diplomat called the timing of this suspicious, trying to distance themselves from it. So why would they go through with an attack . They are under a tremendous amount of pressure because of the sanctions that weve put on them. Their economy is suffering. Their response here is to try to get the rest of the world to put pressure on us to ease up, and they want to do that by raising oil prices and creating an atmosphere of a risk of war. I think it ultimately backfires on them, margaret, and they end up more isolated. Brennan mike morrell, thank you very much for your analysis. Another big story that we are following, late today, Sarah Sanders said shes leaving the white house and going home to arkansas. Sanders has been a fierce defender of the president and often sparred with reporters. Ben tracy is at the white house. She is a special person, a very, very fine woman. Reporter this afternoon, President Trump spoke warmly about one of his longest serving advisers. And i want to thank you for an outstanding job. Thank you, sir and thank you. applause reporter the president called Sarah Huckabee sanders a warrior, perhaps because during her two years as press secretary, she not only spoke for him. Ive addressed your question. Im not going to continue to engage with you. Reporter . She often spoke a lot like him, too. Its, frankly, i think sad and pathetic that a gutless anonymous source could receive so much attention from the media. Reporter sanders could be combative and curt. She rarely hid her feelings for some members of the press corps and their questions. Everybody in this room is only trying to do their job. Isa. Reporter during her tenure, the podium in the Briefing Room gathered dust. Sanders ended the tradition of Holding DailyWhite House Press briefings. Its now been more than 90 days since the last one. Sanders truthfulness has also been questioned. When President Trump fired f. B. I. Director james comey, sanders was pressed by reporters, who said comey was wellliked at the bureau. Ive heard from countless members of the f. B. I. That are grateful and thankful for the president s decision. Reporter when questioned during special counsel Robert Muellers investigation, sanders called her statement a slip of the tongue and not founded on anything. This has been the honor of a lifetime. Reporter but she never lost the confidence of the president , and even while saying goodbye today, she was still playing to an audience of one. Ill try not to get emotional because i know that crying can make us look weak sometimes, right . Brennan ben, today we also heard from a federal watchdog recommending that one of the president s top advisers step down after repeatedly violating the law. Will that happen . Reporter its unlikely to happen. Yes, this independent federal agency is recommending that the president fire one of his top aides, kellyanne conway, for using her office for political purposes namely, for criticizing democrats who are running for president. Thats a violation of whats known as the hatch act. However, its completely up to the president whether or not he fires her. He is unlikely to do so, and a white house official tells us she probably wont even be reprimanded. Margaret. Brennan ben tracy at the white house. Oscarwinning actor cuba gooding jr. Was arrested today and charged with groping a woman at a new york city nightclub. Gooding had voluntarily surrendered to new york police, and he left the precinct in handcuffs. Heres jericka duncan. Reporter it was the smile cuba gooding jr. Flashes on the red carpet, but today, the actor walked into a new York City Police precinct where he was later fingerprinted, photographed, handcuffed, and charged with a crime. I have never seen a case like this one because there is not a scintilla of criminal culpability that can be attributed to mr. Cuba gooding jr. Reporter tmz obtained video of what appears to be 51year old gooding touching the alleged victim at a new York City Club sunday night. Reporter the actor has long been dogged by accusations of bad behavior. Today s lawyer disd another allegation from a second woman who says gooding groped her in 2008. The actors hollywood career started with the 1991 movie boyz n the hood. Ricky reporter and he won an Academy Award for his role in the 1996 film jerry maguire.

Gooding was charged with forcible touching, his attorney call this case overzealous policing. Margaret . Brennan jericka duncan. There was sharp reaction today after President Trump said in an abc interview that he would be open to accepting a foreign governments help in the 2020 campaign. Weijia jiang has more on this. I think you might want to listen. Theres nothing wrong with listening. Reporter President Trump said he would not refuse dirt on a political rival if another country offered it, even though it is a crime for a campaign to knowingly accept anything valuable from a foreign government. You want that kind of interference in our elections . Its not an interference. They have information. I think id take it if i thought there was something wrong, i would go, maybe, to the f. B. I. If i thought there was something wrong. Reporter f. B. I. Director Christopher Wray has said the right thing to do in every case is to report it. Thats something that the f. B. I. Would want to know about. The f. B. I. Director is wrong. Reporter the controversy is unfolding as Congress Continues to investigate russian meddling in the 2016 campaign. Just yesterday, donald trump jr. Testified about meeting with a russian lawyer, promising damaging information about hillary clinton. I will tell you this russia, if youre listening. Reporter thencandidate trump once asked moscow to investigate his opponent. There was an assault on our democracy. Reporter today, House Speaker nancy pelosi said the president is inviting foreign governments to play a role in our elections. The president gave us, once again, evidence that he does not know right from wrong. Its a very sad thing. Reporter even republicans are struggling to defend mr. Trump. Senator lindsey graham, a faithful ally, called him out. I think its a mistake. I think i think its a mistake of law. I dont want to send a signal to encourage this. Reporter other republicans quickly pointed out democratic support in 2016 for that now infamous dossier that contained sensational and unverified claims about President Trumps ties to russia, written by a former british spy. Margaret. Brennan weijia jiang, thank you. Well, police in memphis are appealing for calm after violent protests last night. At least 36 officers were hurt. Many were hit by rocks and bricks. An angry crowd formed after u. S. Marshalls shot and killed a man who was wanted on felony warrants. The marshalls say the suspect, who was armed, jumped in a car and tried to ram their vehicles. Amanda knoxs return to italy today did not go unnoticed. Its knoxs first time back since 2011 when an Appeals Court acquitted her of murder in a sensational case that captivated the country. Seth doane is there. Reporter amanda knox landed in italy, and right back into the media frenzy that trailed her through her murder trial, conviction, and release. Shes here for a criminal justice conference hosted by the italy innocence project, part of a Global Network working to free those wrongly convicted. Knox was released from an italian prison in 2011, after serving four years for the murder and Sexual Assault of her College Roommate meredith kercher. An Appeals Court overturned her guilty verdict, but after she left italy, knox was found guilty again in absentia in a third trial until finally Italys Supreme Court exonerated her in 2015. Earlier this week, she posted a photo with a caption, feeling frayed, and in an essay railed against the mistakes of the italian judicial system, and an irresponsible media, which she writes profited for years by sensationalizing an already sensational and utterly unjustified story. Saturday shell take part in a panel on trial by media. The court of Public Opinion has a tremendous effect on the real courts. Reporter Justin Brooks is the director of the california innocence project. I think it is very, very brave of amanda to come back here. I think its important that shes here because for an entire country, she was the biggest case of someone being convicted, and now shes the biggest case of someone being exonerated. Reporter but margaret, not everyone is so welcoming here. Tonight we spoke with the lawyer for meredith kerchers family, who told us knoxs return to italy is inappropriate and reopens old wounds. Brennan thank you. Seth doane. Next on the cbs evening news, the Measles Outbreak means big changes at a number of summer camps.
