House Judiciary Committee Chairman Jerry Nadler on Sunday stepped up his rhetoric about potential criminal wrongdoing by President Donald Trump and said he plans to request documents from more than 60 people linked to the president.

Nadler, D-N.Y., said during an interview on ABC's "This Week" that congressional Republicans "spent two years shielding the president from any proper accountability."

"It’s our job to protect the rule of law. That’s our core function. And to do that we are going to initiate investigations into abuses of power, into corruption and into obstruction of justice," Nadler said.

On Monday the House Judiciary Committee plans to issue document requests from over 60 people connected to the White House and the Trump Organization, he said. Among those individuals are the president's oldest son, Donald Trump Jr., and Adam Weisselberg, the chief financial officer for the Trump Organization. Nadler expected that the full list of names would be made public on Monday.

"It’s very clear that the president obstructed justice," Nadler said, citing Trump's frequent attacks on special counsel Robert Mueller; his alleged request that the FBI go easy on former national security adviser Michael Flynn; and his admission that one reason he fired FBI director James Comey was to stop "the Russian thing."

"The White House seems to have used its power for personal enrichment in violation of the emoluments clause of the Constitution," Nadler said. If the reports are true that Trump ordered his son-in-law Jared Kushner to be given a top-secret security clearance over the objections of the White House counsel and his intelligence advisers, that would constitute another abuse of power, he said.
