Bloomberg, citing one unidentified source, reported the Republican candidate’s plans to target Cruz's and Kasich's future campaigns on Friday.

The source said that Trump would be willing to invest $20 million or more into the project, which could involve one or two super-PACs.

Trump signaled such a plan in a speech on Friday morning, the day after the close of the convention, while blasting Cruz for refusing to endorse him in remarks before the convention Wednesday night.

“Maybe I’ll set up a super-PAC if he decides to run,” Trump said. “Are you allowed to set up a super-PAC…if you are the president, to fight someone?”

In his speech, Cruz called on Republicans to vote their conscience in November, referring to down-ballot GOP candidates.

And Kasich refused to show up at the convention, despite it being in his home state.
