WASHINGTON (Reuters) - U.S. President Donald Trump is willing to work with congressional Democrats to lower drug prices for Americans and on infrastructure funding, White House adviser Kellyanne Conway said on Tuesday.

Conway said the Trump administration considered those two issues as areas of cooperation between Democrats and the Republican president.

Trump said in January that he expected to see a tremendous decrease in drug prices even as drugmakers have taken steps to raise the prices of medicines starting this month.

According to documents seen by Reuters, nearly 30 pharmaceutical companies have taken steps to end their self-declared halt to price increases this year.

Leaders in the Democrat-controlled House of Representatives say the high cost of prescription drug prices is a top priority for the year. Powerful committees held hearings in January on the matter.

The Republican-controlled Senate Finance Committee has invited executives from five pharmacy benefit managers to testify on April 3 on the rising costs of prescription medicines.
