Relatives of the famous civil rights activist were travelling through the American capital when the driver of their chartered bus suddenly slammed on the brakes to avoid hitting a van which had driven through a red light. Passengers on board - which included King's sister Christine King Farris and family friend and TV personality Omarosa Manigault - were all thrown forward due to the force of the driver's braking. Worrying: The family of Martin Luther King were left shaken after their bus almost collided with a van yesterday. This picture shows members of the King family greeting President Obama Near miss: Christine King Farris, sister of late Dr. Martin Luther King Jr was onboard the bus when it narrowly avoided the collision. She is pictured speaking at yesterday's event As reported by the New York Daily News, the force of the sudden stop resulted in Manigault hitting her head on the seat in front of her. Writing on Twitter afterwards, she said: 'Yikes just got banged up a lil bit on bus- I am ok! #HitMyHead ouch.' The family members had been travelling back from a rally honoring the 50th anniversary of the 'I Have a Dream' speech in Washington. According to TMZ, the driver of the bus needed hospital treatment following the near miss. King's family had earlier rang a 'bell of freedom' outside the Lincoln Memorial to mark the moment he finished his famous speech. Sore: King family friend and TV personality Omarosa Manigault tweeted about the near miss Despite being surrounded by presidents, senators, a first lady and even Oprah Winfrey, Martin Luther King Jr."s adorable granddaughter Yolanda Renee King was the star of the show. The five-year-old kept her cool as Barack Obama hugged her mother and father and even gave her a tickle as she stood regally at the forefront of the event honoring her grandfather's march on Washington. The King family rang a bell at the steps of the Lincoln Memorial that once hung in the 16th Street Baptist Church in Birmingham, Alabama, which was the target of a racially motivated bombing that killed four little girls in 1963. So cute! Not even a president could take the spotlight off of Martin Luther King Jr.'s adorable granddaughter, 5-year-old Yolanda Renee King at the 50th anniversary of the March of Washington Icon: Dr King is pictured with the Lincoln Memorial as a backdrop moments before he made his famous speech In front of tens of thousands of spectators, President Obama urged America to continue fighting for the equal nation Martin Luther King Jr. envisioned as he delivered a rousing speech marking 50 years since the activist's iconic 'I Have a Dream' address. Speaking from beneath the Lincoln Memorial in Washington D.C., the president celebrated how far America has come since Dr King's speech on August 28, 1963, which gave a 'mighty voice to the quiet hopes of millions'. But he said there was still much to be done to honor the lives that were lost during the civil rights movement. Impassioned: Thousands of people gather for a march 'For Jobs and Justice' down Pennsylvania Avenue toward the Lincoln Memorial in Washington DC on Wednesday morning But we would dishonor those heroes as well to suggest that the work of this nation is somehow complete. 'The arc of the moral universe may bend towards justice, but it doesn't bend on its own. To secure the gains this country has made requires constant vigilance, not complacency. There were also impassioned addresses from former Presidents Bill Clinton and Jimmy Carter, who commented on America's unfinished business, with Clinton saying: 'A great democracy does not make it harder to vote than buy an assault weapon.'
