House Intelligence Chairman Adam Schiff said special counsel Robert Mueller isn't done serving his country and should testify before Congress about his investigation into Russia's interference in the 2016 presidential election.

"I was disappointed ... to see such a profound reluctance to testify," The Democrat from California said on ABC's "This Week" on Sunday. "I think he has one last service to perform. It's not enough merely to speak for 10 minutes and say, 'I'm not going to answer questions for Congress and the American people.' There are a great many things that are not in the report."


Mueller delivered remarks Wednesday as he closed up shop as special counsel and said that he did not intend to testify before Congress. Mueller characterized his report as his testimony, emphasizing that it did not clear President Donald Trump of misdeeds or criminal acts such as obstruction of justice.

"If we had had confidence that the president clearly did not commit a crime, we would have said so," Mueller said at the news conference.

That has not satisfied House Democrats, who continue to probe into a litany of the president's affairs, from his actions during the 2016 presidential campaign to his personal finances.

Schiff said he wants to ask Mueller whether Russia has collateral on Trump, keeping him in its influence, and about a number of other topics that were not in the report. If Mueller does not willingly testify, Schiff said he would recommend issuing Mueller a subpoena.

Though pressing for more information, Schiff did not say that impeaching Trump was an immediate priority. The congressman continued to toe House Speaker Nancy Pelosi's line of focusing on the party's legislative agenda rather than impeachment now that Democrats have a majority in the House.

Rep. Jim Jordan (R-Ohio), a vocal Trump ally, retorted on ABC that Mueller had had ample time to establish whether Trump had obstructed justice. Still, Jordan said he had questions for Mueller and did not oppose having him testify.

"Bob Mueller had 22 months, $30 million, 19 lawyers, 40 FBI agents, 500 witnesses, 2,800 subpoenas. If he could have accomplished obstruction, he would have done it," Jordan said.
