From The Washington Post:

Republicans on a Senate panel voted Thursday to authorize a sweeping set of potential subpoenas targeting the origin of the federal investigation into President Trump’s 2016 campaign, with a focus on several senior members of former president Barack Obama’s administration.

The vote in the Senate Homeland Security and Governmental Affairs Committee represents the escalation of an election-year GOP campaign to recast the investigations that consumed much of the president’s first two years in office as the product of backroom manipulation, corner-cutting and subterfuge orchestrated by Trump’s political enemies.

…

“I think they are reacting to public pressure,” said Tom Fitton, president of Judicial Watch, which had led the pro-Trump campaign against the Obama Justice Department. “There are tens of millions of Americans who are exceedingly frustrated that there’s been zero accountability to date, and I think Republicans are all of a sudden recognizing that. That’s the number one question I get asked: Why hasn’t anyone gone to jail? Why hasn’t anything been done? And the Senate hasn’t done much.”

While Graham has focused his committee on actions inside the Justice Department in 2016 and 2017, Johnson has focused his interest in the State Department — and alleged efforts by officials there to foment law enforcement interest in the allegations of British intelligence operative Christopher Steele. That has been aided by troves of documents handed over by the Trump administration — and more could be on its way.
