President Donald Trump again attacked the Federal Reserve on Tuesday after the weakest U.S. manufacturing reading in 10 years.

In a tweet, the president wrote Fed Chair Jerome Powell and the central bank "have allowed the Dollar to get so strong, especially relative to ALL other currencies, that our manufacturers are being negatively affected." He contended the Fed has set interest rates "too high."

"They are their own worst enemies, they don't have a clue," he wrote. "Pathetic!"

Trump tweet: As I predicted, Jay Powell and the Federal Reserve have allowed the Dollar to get so strong, especially relative to ALL other currencies, that our manufacturers are being negatively affected. Fed Rate too high. They are their own worst enemies, they don't have a clue. Pathetic!

As his trade war with China rages on, Trump has repeatedly blamed the Fed's interest rate policy for concerns about a slowing U.S. economy. He has contended the central bank has not moved quickly enough to ease monetary policy — though the Fed has cut its benchmark funds rate twice this year.

The Fed did not immediately respond to a request to comment.

Trump's tweet comes after the Institute for Supply Management's manufacturing reading fell to 47.8 in September, down from 49.1 in August. A reading below 50 shows a manufacturing contraction.
