Here is how many times protestors interrupted Donald Trump's speech

An organisation called the Michigan People's Campaign said it was behind the protest.

Protestors interrupted a major economic speech by Donald Trump at least a dozen timesby jumping up and shouting in a co-ordinated effort to disrupt the Republican presidential nominee's remarks.

One at a time, at least a dozen women seated throughout the audience stood up and yelled "Mr Trump", but their continued shouts were quickly drowned out by boos as security led them from the room.
