Trump increasingly frustrated with homeland security secretary Mullin

The president of the United States is unhappy with the person who leads homeland security, a man named Mullin.

Mullin's job includes working to send people out of the country who do not have permission to be there.

The president's loudest supporters got angry about some things Mullin said.

Those supporters believe Mullin should be sending away as many immigrants as possible.

They also want fewer people coming into the United States overall.

One supporter, Laura Loomer, talks to the president often.

She wrote on social media that the president should fire Mullin.

She says Mullin has done absolutely nothing to make deportations happen faster.

The secretary's own explanation for his comments is not included in the article.

People disagree strongly about how many immigrants a country should welcome, which is why this is a big argument.
