"If you announce great numbers, they raise interest rates," Trump said in the speech. "When the market goes up, they should lower rates."

Trump has disagreed sharply with the interest rate strategy of the independent Fed, chaired by Jerome Powell, and has pressed for lower rates, faster. He maintains that a rising stock market should cause the Fed to cut its benchmark interest rates in order to further boost economic growth.

But the Fed has the legal responsibility of keeping prices stable and maximizing employment. Slashing rates as Trump has suggested could push more money into the U.S. economy and worsen inflation.

Trump says he plans to announce health care plan this week

The president didn't specify when he will announce his plan but he and Republicans have been under increasing pressure to address Americans' health care costs, especially as subsidies for those who get coverage under the Affordable Care Act expired at the end of last year.

Trump reiterated his wish to have money be sent directly to consumers to buy health insurance rather than sending money to insurers.

He also promoted his agreements with various drug manufacturers to lower the costs of their prescription drugs in the U.S. and said his party should win midterm elections this year based on that alone.

"We should win the midterms in a landslide," he said.
