0:00:11 > 0:00:14Hi, I'm Martin and this is Newsround.
0:00:14 > 0:00:18First, America is waking up today to a new president - Donald Trump.
0:00:18 > 0:00:22The billionaire businessman and former reality TV star has
0:00:22 > 0:00:25taken charge of the US, after a huge inauguration
0:00:25 > 0:00:35ceremony yesterday.
0:00:38 > 0:00:40Leah was there in the Capitol, Washington.
0:00:40 > 0:00:43This is the moment Donald Trump officially became the 45th president
0:00:43 > 0:00:44of the United States.
0:00:44 > 0:00:45I, Donald John Trump, do solemnly swear that
0:00:45 > 0:00:48I will faithfully execute the office of President of the United States.
0:00:48 > 0:00:51In his speech afterwards he told the crowds that he
0:00:51 > 0:00:53would put America first.
0:00:53 > 0:00:57I will fight for you with every breath in my body and I will never,
0:00:57 > 0:01:05ever let you down.
0:01:05 > 0:01:09The ceremony was also timed to say goodbye to outgoing
0:01:09 > 0:01:14President Barack Obama who flew out in a helicopter.
0:01:14 > 0:01:19Thousands of people came to watch Trump's inauguration.
0:01:19 > 0:01:22Since he's going to be running our country,
0:01:22 > 0:01:24I want to help support him and just come see him.
0:01:24 > 0:01:27It was pretty exciting because this is the moment
0:01:27 > 0:01:31that only certain people see.
0:01:31 > 0:01:33He can't really do anything too terrible so I'm interested
0:01:33 > 0:01:36to see what he does.
0:01:36 > 0:01:38It's an historical moment so I'm happy to be here.
0:01:38 > 0:01:40We have a new president now.
0:01:40 > 0:01:44Not everyone here is celebrating Donald Trump.
0:01:44 > 0:01:48These people are protesting outside his new hotel in Washington, DC.
0:01:48 > 0:01:51They are unhappy and they don't think he's the right
0:01:51 > 0:01:53man to run the country.
0:01:53 > 0:01:57There are more protests that are expected here, too.
0:01:57 > 0:02:00I really have no idea how he will run this country.
0:02:00 > 0:02:03So far it doesn't seem like he's been doing the best kind of job.
0:02:03 > 0:02:08I hope that he doesn't, like, pick fights with other
0:02:08 > 0:02:12countries and start a war.
0:02:12 > 0:02:17Try not to mess America up that much in four years.
0:02:17 > 0:02:22Then it was time for the big parade.
0:02:22 > 0:02:26And now, for the first time, the new president of America,
0:02:26 > 0:02:29Mr Donald Trump, is here along the parade route, greeting people
0:02:29 > 0:02:35for the very first time.
0:02:35 > 0:02:39He's our new President, I can't do anything about it so...
0:02:39 > 0:02:43I feel like he's a great businessman and I feel he will do a great
0:02:43 > 0:02:44job as our president.
0:02:44 > 0:02:46I feel the same way.
0:02:46 > 0:02:48I think he's going to do a lot of things.
0:02:48 > 0:02:50I think he'll do great.
0:02:50 > 0:02:54So, as Donald Trump wakes up to his first morning in the White House,
0:02:54 > 0:02:58the country will be waiting to see if he can live up to his promises.
0:02:58 > 0:03:02And on his first day as president, Donald Trump will be waking up
0:03:02 > 0:03:06to thousands of women marching as part of a big campaign to raise
0:03:06 > 0:03:10awareness for gender equality and women's rights.
0:03:10 > 0:03:19This is because protestors think their rights could be under
0:03:23 > 0:03:25threat from the new president, Donald Trump, after rude comments
0:03:25 > 0:03:27he has made about women in the past.
0:03:27 > 0:03:29Marches are taking place in 32 different countries
0:03:29 > 0:03:31with the biggest in Washington DC, the capital of America.
0:03:31 > 0:03:34If you want any more info on the inauguration or Donald Trump

0:03:49 > 0:03:56I'm Amar.
0:03:56 > 0:03:59These guys are the Junior World Champions in their age group.
0:03:59 > 0:04:02Jujitsu is important to me because I get to see new people
0:04:02 > 0:04:06and make new friends.
0:04:06 > 0:04:09It helps me express myself, really, like fighting and it's a good way
0:04:09 > 0:04:11to relax after a long day at school.
0:04:11 > 0:04:14I like travelling around the world and winning competitions.
0:04:14 > 0:04:23Jujitsu is a martial art which combines the grappling
0:04:23 > 0:04:25of judo with the kicking and punching of karate and boxing.
0:04:25 > 0:04:27Opponents punch and kick each other to score points.
0:04:27 > 0:04:30And the person with the most points, wins.
0:04:30 > 0:04:32There are lots of different types of jujitsu, including Brazilian
0:04:32 > 0:04:34style, which these guys do.
0:04:34 > 0:04:38Which doesn't involve kicking.
0:04:38 > 0:04:42I think I'm good at jujitsu because I put my heart and soul into it.
0:04:42 > 0:04:45I train as much as I possibly can.
0:04:45 > 0:04:52I am really good at jujitsu because I have been
0:04:52 > 0:04:53practising for four years.
0:04:53 > 0:04:56I like beating the boys in it because it gets them really annoyed.
0:04:56 > 0:05:00It helps me to just to look after myself when there is a bully
0:05:00 > 0:05:01who is trying to hurt me.
0:05:01 > 0:05:05Since I enjoyed it, I kept on doing it and then somehow I turned out
