Lawmakers in South Carolina are expected to take up legislation next week to remove the confederate battle flag from the State Capitol in columbia. One opponent of the flag wasnt waiting for that. Last weekend she took matters into her own hands. Maam, come down off the pole axelrod with just a harness and a pail, newsome scaled the pole and took down the flog. Tell me whats going on. I was feeling it was like a david and goliath moment there. Axelrod newsome teamed up with james tyson in what they saw as a classic example of civil disobedience. So theres a school of thought that says, hang on, the legislator is going to come back and meet and deal with this, let the process work. The process is broken. Those laws that are put in place, this long process you have to go through to remove the flag. So were here and weve had nine people massacred in a hate crime and were sitting around saying, well, we cant take the flag down because of this law that was put in place. Youve just got to do the right thing sometimes. The flag in South Carolina has been fought about and debated now for years and people say its a very complex issue. But this was a very simple act. Its really not that complicated. People might have other feelings about their Southern Heritage or whatever and you want to fly it or put it on your bumper sticker, back of your car, have a beach towel. Nobody can tell you you cant do that its free freedom of speech but when it comes to the capitol its not a complex issue at all. Axelrod newsome is due in court july 27. She and tyson face charges that carry up to 5,000 in fine and three years of jail time.

The Confederate Flags are gone, only leaving stars and stripes and you can buy a tshirt or mug with the rebel flag but only if it also displays the american flag. The Confederate Flag is still widely displayed in the museum and battlefield itself. Weve always told both sides to have the story at gettysburg military park. Its our passion to tell the whole history. To me its history. Reporter lee houser wears the uniform of isaac trimble, a general. We have ancestors on the confederate side, im honoring them by flying the flag. Reporter scott wilson plays a midlevel officer. They say theyre pained by the fact that some people including ku klux klan and white supremacist such as alleged killer dylann roof have long used the flag as a symbol of racism and hate. Some people use it for other things which is an injustice. If i could take it down, i would in a heart beat, but i cant, free speech.

I even accept that i live with a higher risk of stroke due to afib, a type of irregular heartbeat, not caused by a heart valve problem. But i wont accept giving it less than my best. So if i can go for Something Better than warfarin. I will. Eliquis. Eliquis. Reduced the risk of stroke better than warfarin plus it had less major bleeding than warfarin. Eliquis had both. That really mattered to me. Dont stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. While taking eliquis you may bruise more easily and it may take longer than usual for any bleeding to stop. Seek immediate medical care for sudden signs of bleeding like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. I accept that im not as fast, but im still going for my personal best. And for eliquis. Reduced risk of stroke.

Axelrod one of the worlds most Ambitious Construction projects is going on in secret. The chinese are building islands on reefs in the c. They say the area is theirs, dismissing claims by vietnam taiwan and the philippines. Seth doane set out to take a look. Reporter the chinese denied us permission to see their new islands so we hired filipino fishermen to take us as close as we could get. Satellite imagery shows china is adding on average more than three and a half acres every day. One of the reasons the South China Sea is so valuable is it has 7 billion barrels of proven oil reserves. Thats the Oil Consumption of the entire United States for a year. This rickety boat usually carries grouper and squid not journalists. Filipinos told us they see china as a bully and these fishermen feared an encounter with chinese patrols. As we were first approaching the reef, you could just see one crane. Now as we get closer, you can see a number of cranes up and down the length of this island. The u. S. Believes china will turn these islands into military bases. The u. S. Flew a surveillance plane over the disputed waters and American Warships patrol the region as a warning. As we got closer to the reef, the chinese sent a warning signal through the haze. Theyve now flashed several Warning Signals at us. Our captain is starting to get nervous. He tells us its time to get out of here. Romulo barcoma later told us he felt it was too dangerous to go any closer. I dont likely know the chinese, so we cant trust them, he said. The fear is tensions could spark a conflict and draw the u. S. Further into a dispute in these already turbulent waters. Seth doane cbs news in the South China Sea.
