What do you know about his father . His father seemed to care what we thought. And what distinguishes his son, he doesnt seem to care what any of us think, and hes certainly not been interested in any, any phase of negotiation. Is he sane . Sane from the point of view of running that country, of making sure that hes consolidated power, making sure that everyone works for him, yeah, yeah. We know that the North Koreans have been successful in building missiles and successful in detonating Nuclear Weapons in tests. The real trick is putting those two things together. What are the chances that the North Koreans are close . You know, very hard to say. But the feeling is that within the next four years , they coul have a Missile System with a Nuclear Warhead that would be credible. Whether it would finally work when they pushed the button, hard to say, but it would be credible. And any president would have to consider that as a real threat. Former ambassador chris hill.

The cbs evening news, with arnold zinker, substituting for Walter Cronkite during the strike. Yes, Walter Cronkite was on strike. The Union Representing tv personalities was on a walkout. John daley and others were off the air and on the street. Newscasters were replaced by management. But who would subf for cronkite . An a to z search led to arnold zinker, a 28yearold cbs executive who had worked his way through school doing radio broadcasts. I said ive never done television. They said youre going to do the cbs morning news, then they said stay around and do the midday news. And with about an hour of experience under his belt, he was called in to fill in for cronkite. Planes have been using a massive bomb. He got more than 3,000 fan letters. Its the standard case of the understudy. The star goes out for whatever reason, and an understudy nobodys ever heard of sits in, sits in the chair, gets good reviews. Anchor was born.

After weeks at the pinnacle of network news, zinker was told he had a great future ahead of him. Thats when i decided to go to boston and do the news. Bitten by the anchor bug, he tried his hand at local tv, and years later he returned to cbs briefly in a 60 minutes cameo, in his new career, training executives to master the public spotlight. He travels the country, preaching the gospel according to zism nker. Now a half century after zinker made headlines, he is a footnote. Tv trivia for 100. Arnold zenker replaced this newsman. This has been the cbs evening news with Arnold Zenker substituting for Walter Cronkite. Thats the overnight news for this wednesday. For some of you the news continues, for others, check back later for cbs morning news and cbs this morning. From the Broadcast Center in new york city, im scott pelley. This is the cbs overnight news. Im don dahler. President trump has summoned all members of the senate today. Tensions are rising in asia. The north is expected to conduct another nuclear test. An armada is south of the korean peninsula. And trump is being asked to show restraint. Adriana diaz has the story from beijing. Reporter President Trump is also ramping up his war of words. Monday he said kim jong un is not a strong militarily as he says and also blamed the International Community for not doing more to rein him in. The status quo in north koreas also unacceptable. Reporter at the white house on monday, President Trump scolded members of the u. N. Security council for falling short in their dealings with north korea. The council must be prepared to impose additional and stronger sanctions. Reporter in a show of force, intended to send a warning to north korea, the Uss Carl Vinson Strike Group along with two japanese destroyers are rapidly approaching the korean peninsula. There theyll be joined by south korean ships. The uss michigan, a nuclearpowered submarine also arrived in the port city of pusan today. Angered by the buildup and threat of further sanctions, the regime has stepped up its rhetoric, unveiling new weapons while lashing out at its adversaries. North korean media called the movement extremely dangerous, saying the u. S. Should consider carefully any catastrophic consequence. This raises the stakes. Reporter analyst Jonathan Polak says the white house needs to proceed cautiously. With the United States and others talking far too loose lay of the prospects of a preemptive strike, thats what would trigger retaliatory actions by north korea. Reporter its also been three days since tony kim was detained at north koreas airport. We could stumble needlessly into what would be the biggest crisis in east asia since the United States intervened in the korean war in 1950. Reporter to avoid that, President Trump is working closely with china. Hes already spoken with chinas president twice in the past two weeks. First daughter and white house adviser, ivanka trump continues her visit to germany. Shes taking part in an international womans summit. But it wasnt all smiles and handshakes. Ivanka actually got booed by the audience when she described her father as quote a tremendous champion of supporting families. Mark phillips is in berlin. Reporter this is no ordinary visit by an ordinary white house official. This is three visits in one by ivanka trump the first daughter, the president ial adviser and the businesswoman. Its complicated, like the state of u. S. german relations right now. On the face of it, ivanka trump has come to berlin for a highpowered conference on promoting the role of working women. Its one of her pet issues. But shes also here because Angela Merkel knows an opportunity when she sees one. When the german chancellor went to washington to meet ivankas father, the atmosphere bordered on icy. So when Angela Merkel met ivanka and invited her to the berlins Women Conference it was more than playing to the first daughters interests. Political analysts say it was a way to use a side door to get into the white house. You take what you get. Reporter and what do you think you get with her . You get access to donald trump and maybe a moderating effect to donald trump, because hes also surrounded by people who are less moderate and seem to be more radical. Reporter ivanka, the special adviser to the president , did tell gayle king that when it comes to trying to influence her father on issues that she cares about, shes not shy. This particular title was about giving critics the comfort that im holding myself to the highest ethical standard. But ill weigh in with my father on, on the issues i feel strongly about. Reporter but this visit isnt about issues. Its about trying to jump start a stalled relationship. We actually dont know what ivanka trumps position is on the issues of contention between washington and berlin right now. Russia, nato refugees. We do know that the Trump Administration has yet to appoint its own ambassador to germany, so that right now go terms of highlevel diplomacy, ivanka trump is it.

The shows are often shot to look more like a movie, taking longer in production, which keeps writers tied up for the same amount of time while making less money. The average income for writers has gone down, 23 . Its about not being able to sustain yourself. Reporter wrietders are asking for higher script fees. Bigger residuals from streaming media and larger contributions to their health plans.
