Trump and his fellow Republicans have sought to focus on the caravan and immigration ahead of the midterm elections, where his party is fighting to maintain control of the House and Senate.
Trump said his lawyer, former New York City Mayor Rudy Giuliani, would release a response to the report that Mueller is expected to finalize in the coming months.
Trump has denied any wrongdoing and has urged more efforts from Republicans to defend him and challenge the impeachment inquiry, as depositions are turning to the White House and a series of witnesses have testified behind closed doors before House panels leading the investigation.
Trump appears concerned, tweeting on Monday: "Our economy is very strong despite the horrendous lack of vision by (Federal Reserve Chairman) Jay Powell. The fed (funds rate), over a fairly short period of time, should be reduced by at least (one percentage point). If that happened, our economy would be even better and the world economy would be greatly and quickly enhanced — good for everyone!"
Trump, however, also said the summit might not happen.
Trump's announcement on Twitter came after the deputy director of national intelligence, Sue Gordon, resigned. She said in a note to Trump that stepping down was not her "preference," but added, "You should have your team."
