Three weeks later on Sunday, September 15, a bomb exploded at the 16th Street Baptist Church in Birmingham; by the end of the day, four African American children had died in the explosion, and two other children were shot to death in the aftermath.[329] Due to this resurgent violence, the civil rights legislation underwent some drastic amendments that critically endangered any prospects for passage of the bill, to the outrage of the president. Kennedy called the congressional leaders to the White House and by the following day the original bill, without the additions, had enough votes to get it out of the House committee.[330] Gaining Republican support, Senator Everett Dirksen promised the legislation would be brought to a vote preventing a Senate filibuster.[331] The legislation was enacted by Kennedy's successor President Lyndon B. Johnson, prompted by Kennedy's memory, after his assassination in November, enforcing voting rights, public accommodations, employment, education, and the administration of justice.
