Donald Trump Jr. is preparing to dive into the 2018 midterm elections.

What's next: He wants to use his influence within the Republican base to "expand our majority in the Senate and protect our majority in the House," said a source close to the president's son. Expect Don Jr. to be raising money for Republican candidates and staging rallies.
