President Trump on Tuesday predicted the stock market would jump even higher after Congress passes the Republican tax reform plan, which is expected to happen Tuesday in the House.

"Stocks and the economy have a long way to go after the Tax Cut Bill is totally understood and appreciated in scope and size. Immediate expensing will have a big impact. Biggest Tax Cuts and Reform EVER passed. Enjoy, and create many beautiful JOBS!" Trump tweeted Tuesday morning.

The tax bill's passage would mark the first major overhaul of the tax code in more than three decades. The House is expected to pass it easily Tuesday, and it could pass as early as Tuesday evening in the Senate, where the vote is much closer.

Sen. John McCain, R-Ariz., will not be back for the vote, which means Republicans can only lose one vote to have it pass with a majority.

Trump also celebrated the Dow Jones' historic 5,000 point surge in 2017.

"DOW RISES 5000 POINTS ON THE YEAR FOR THE FIRST TIME EVER - MAKE AMERICA GREAT AGAIN!" Trump wrote.
