The brother of one of the victims of the Parkland shooting has claimed he was shut out of March for Our Lives because his speech 'didn't fit the agenda.'

Hunter Pollack's 18-year-old sister Meadow was one of 17 killed after a student opened fire at Marjory Stoneman High School in Florida on February 14.

On Saturday, David Hogg - one of the organizers of the march - said a miscommunication had stopped Pollack from speaking at the rally in Washington on March 24.

Pollack instead gave that speech to a crowd of more than 1,000 in his Coral Springs backyard at an event in honor of his sister.

Hogg shared a video of the speech after Pollack posted it on Twitter, writing: 'A miscommunication led to Hunter not being able to speak at the march... I would like you to hear it now...'

Pollack responded: 'Thank you , I appreciate you pushing out my video but there was no miscommunication my speech didn't fit in to the agenda.'

Pollack previously said he was set to give a speech, but wasn't allowed.

'I was going to give a speech about Meadow and how devastated I am and how we need to make change, but they won't allow me to put my voice out,' he told local10.com.

Pollock was questioning if 'their political agendas' were the reason behind his omission from the rally - where many survivors spoke on gun control, according to Fox News.

But another march organizer Ryan Deitsch said Pollack was invited but 'never showed up.'

Both Pollack and his father Andrew have been advocating for school safety since Meadow's death.

On Saturday, they held an emotional biker ride fundraiser where they were joined by other students including Hogg.

An estimated 650 bikers rode 43 miles through South Florida to raise funds to build a playground for kids in the teenager's honor.

HUNTER POLLACK'S SPEECH In my heart, I know this is not a mission driven by politics nor should it be dictated by the left or the right. This is not a mission specific to color, religion or economics but rather it's a mission of love. It's a mission of safety built upon a foundation filled with common sense and fueled by a common denominator that can bring together every American across this great country. The one common denominator we all share is a desire to live. We all want to live to the greatest possible greatest life possible. My sister Meadow Pollack was living an amazing life filled with love passion dreams family and fun. She had so much to offer this world she had so much ahead of her. But because we as a school and we as a community and we as a society and we as a state and we as a nation failed to protect her, my baby sister is no longer a part of this occasion we call life. What pains me most is that her beautiful life was not lost through an incurable disease or a freak accident. She's gone because our schools are not safe. She's dead because the madness of one young man and his determination to kill was greater than our desire to stop him. Remembering Meadow and the Parkland 17 is something that we must all vow to here today.We must promise to take action each and every day till we protect the students of this country. We must protect our students and our schools in the same way we do the patrons at an NFL stadium and the passengers at an airport and the diamonds in a jewellery store. We the students of America are the most valuable assets this nation has. Therefore we hereby put all the leaders and parents of this country on notice today. Today we demand you to put a value on our lives and to protect us and above anything else. We as the students of this country must take our anger and take our pain and our desire to live this life to the fullest and we must channel it into a mission that is obtainable, one that can be achieved without heavy debate, one that everyone can agree upon today, tomorrow and for decades to come. What happened at Parkland should have resulted in immediate action across America but it has not. Two weeks ago, a student in Utah tried blowing up a school with a bomb and then this week in Maryland, we lost another life in a school shooting. The weapon may be different, but the objective is the same. So we need to protect our schools from the killers that wanna kill. The hatred and sickness that fuels a killer to kill innocent students is something most of us will never understand but that doesn't mean its something that we can ignore. We need to be on a mission to stop these monsters before they take action inside the school. We must demand our leaders help those who are sick, but we also demand that they protect those of us who are not In closing, I ask you to say my sister's name to yourself – it's such a beautiful name. Meadow. Yep, Meadow. If you say her name, it's impossible not to feel the beauty of who she was and who she will always be. Meadow… it makes me think of a sunny day like this one. A day where the sun shines on our youth and shines on a desire to live safe and happy life I can feel Meadow right now, she's asking us to come together. She wants us to thank the families of the victims like my dad Andrew who has worked tirelessly and I've watched him. He's the man. And Mr Ryan Petty and all others who are turning their grief into something positive. She says thank you for continuing to fight for the survivors and students of all ages. Meadow's asking us to be smart in the love and to share the common denominator we share. Embrace this life, make the most of it. Don't let it be wasted, do not allow it to be taken away by a weapon of any kind. To my sister Meadow who's up in heaven, I promise you here today that Dad and I along with millions of people at our side will do our part in making schools safe so that this never happens again. We vow to protect American children in the way you should have been protected. We will keep them safe from the killers and all weapons they use. Until we meet again Meadow, I miss you like crazy. I love you, we all love you. May you shine on us today and every day going forward. Advertisement

The 52-year-old father (left) is using the money raised to build a park to honor his daughter (pictured right). He said a tribute fountain will be placed in the park to remember all the victims from the shooting

'Meadow was amazing,' Andrew Pollack said to the Sun-Sentinel. 'There is nothing she couldn't do or get from me. She was my little girl.'

The daughter, who was 18 at the time of the shooting, was shot dead with 16 other people when Nikolas Cruz decided to open fire on the high school.

Her grieving father helped design a park in her honor that would include a water feature to memorialize all the people who died that day.

His goal is $1million to help build and maintain the park. So far he has raised a little over $150,000.

Pollack told the Sun-Sentinel that he wants to include other Parkland survivors on the plans for the park. A location has not yet been picked for the memorial.

Hundreds of people attended the event on Saturday to remember Meadow's life and raise more money for the memorial.

'This is nothing political,' Pollack said to the newspaper about the gathering. 'We're all Americans, and we want our kids to be safe.'

The father, who was present when Florida Gov. Rick Scott signed a new safety bill for schools on March 9, has been vocal about both parties working together to keep schools safe instead of debating gun laws.

An estimated 650 riders drove 43 miles through South Florida to Coral Springs, Florida. Pollack was among them riding on his motorcycle

Pollack described his daughter as 'amazing' and said a piece of him went with his daughter when they had to bury her

The new bill provided $400million for mental health, school safety programs and even allowed the arming of some school staff.

Pollack thanked the crowd for attending the fundraiser and admitted that a part of him was now buried with his daughter.

'Evil went into that school that day and it knocked on my door and took my daughter,' he said. 'I'm not about to let that happen again.'

Some notable attendees at the fundraiser on Saturday were students David Hogg and Jaclyn Corin.

Hogg especially has been vocal about gun-control laws since the shooting and has targeted the National Rifle Association as the problem.

Pollack said he has so far raised $150,000 for the new park. His goal is $1million to be used to build and maintain the park

Meadow Pollack, 18, was killed with Nikolas Cruz opened fire at Marjory Stoneman High School in Parkland, Florida

He posted a video during the fundraiser of Hunter Pollack, Meadow's brother, speaking about his sister.

The students sparked controversy from people in the Republican party after March for Our Lives because students who supported guns were allegedly 'not allowed' to speak during the event.

In the tweet, Hogg said Hunter was unable to speak at the march because a 'miscommunication', so he encouraged everyone to watch his speech during the fundraiser.

Hogg has faced attacks from members of the far-right after he became outspoken about the NRA and gun laws.

His recent feud with Fox News television personality Lauren Ingraham forced her to issue an apology after she attacked him for not getting into all of the universities he applied to.

Similarly, actor and musician Frank Stallone had to reign in his critiques of the teenager after he posted a variety of vile tweets against him.

'This David hog p***y is getting a little big for his britches,' he tweeted on Saturday afternoon.

Then on Sunday he apologized, expressing remorse for what he called 'irresponsible words' and saying: 'After what these kids went through, I'm deeply ashamed.'
