Washington (CNN) Maryland Democratic Rep. Elijah Cummings said Sunday that once his party retakes control of the House, he hopes President Donald Trump's estranged former attorney Michael Cohen will testify before Congress.

"I certainly would like to see him come in the month of January," Cummings said on CNN's "State of the Union."

The request by Cummings, who is expected to take over the chairmanship of the House Oversight and Government Reform Committee next month, for testimony from Cohen would come ahead of the former Trump attorney's three-year prison sentence due to start in early March.

A longtime attorney and "fixer" for Trump, Cohen has since become sharply critical of the President and described his role working for Trump as covering up his "dirty deeds."
