Capitol Hill this week has been dominated by continuing revelations about ties between members of the Trump camp and Russia, including fallout from the resignation of national security adviser Michael Flynn.

The Nebraska Democratic Party on Thursday urged the state’s congressional delegation to formally request an independent bipartisan investigation akin to the 9/11 Commission.

But there’s little evidence that Republicans are ready to go that far. Many of them have suggested that the matter can be ably handled by the Senate Intelligence Committee.

“The intelligence committee is going to have hearings, they’re going to be investigating it, they’re going to be doing their job of oversight,” said Sen. Deb Fischer, R-Neb., a member of the Senate Armed Services Committee. “I think that’s the way it needs to happen.”

Sen. Ben Sasse, R-Neb., also a member of the Senate Armed Services Committee, said he supports a congressional investigation.

“For more than a year, I’ve been clear on Russia — and frankly this has been conservative orthodoxy well before Mitt Romney identified Moscow as our ‘number one geopolitical foe’ — Putin and his thugs are fundamentally at odds with America’s interests,” Sasse said in a statement.

“I’m obviously in support of a full congressional investigation into Russia’s influence campaign in the United States and the events surrounding Gen. Flynn’s resignation,” Sasse added. “Every member of Congress owes it to the American people to view this not through partisan labels but through our constitutional duty to conduct honest congressional oversight that restores public trust in self-government.”

Ernst also is a member of the Senate Armed Services Committee. She recently led a hearing on Russia’s placement of advanced air defense systems, surface-to-surface missiles and coastal defense weapons that bracket U.S. friends and allies.

She also pointed to Russia’s cyberwarfare activities and ongoing military campaigns.

“The aggression of President Vladimir Putin towards his neighbors and his blatant disregard for their sovereignty and territorial integrity was on full display when he invaded Ukraine and illegally annexed the Crimean peninsula,” Ernst said.

The United States must seek to counter those actions, she said, noting that she isn’t sure about the administration’s strategy.

“I don’t know what their posture is right now, especially as we sort through the Gen. Flynn resignation,” Ernst said.

She and other senators recently put their concerns into a letter to Trump, recommending that he keep U.S. sanctions against Russia and suggesting the imposition of more sanctions as warranted.

They said the United States should not enter into any agreements with Russia regarding Syria’s future until Moscow halts military operations there. And they called for the United States to recognize and counter cyberwarfare by Russia.

“Russia is not our friend, and any threat to our nation’s cybersecurity must be met with a firm response,” Ernst said.

A bipartisan group of senators and House members has introduced legislation that would require Trump to come to Congress if he wanted to lift sanctions against Russia and give lawmakers a chance to block such a move.

None of the senators or House members from Nebraska or Iowa have signed on to the legislation, although Ernst said she was still looking at its details.

Earlier in the week, Sen. Chuck Grassley, R-Iowa, was asked about Russia and its alleged interference in the U.S. election and said America isn’t “hands-free” in that area given its own history of interfering in other countries’ elections.

Grassley also expressed concern about those leaking information to the press.

“I think that we need to start considering that it’s not only dangerous and scary that some foreign power attempts to influence our elections, but it may be even scarier that intelligence officials in our own government may be trying to undermine our government,” Grassley said.

During an interview with CNN this week, Rep. Steve King, R-Iowa, also complained about the leaking.

He said that Flynn had been the subject of a “political assassination” and that the people leaking are violating the law to undermine Trump. He raised the hypothetical situation of the president planning a strike against terrorists and members of the intelligence community who disagree with the plan leaking it to the media.

“We’re at great risk if we have these kind of moles with this low level of integrity that are leaking information out to move their political agenda,” King said.

‘They’re Scared’: Immigration Fears Exacerbate Migrant Farmworker Shortage

With some exceptions, farmers have generally applauded the administration’s moves to curb regulation. But they worry about the crackdown on illegal immigration, since many farmworkers are undocumented. And farmers are deeply at odds with the administration’s trade policies.

The Farm Bureau was counting on a big Asia-Pacific trade deal to boost exports to Japan and other markets. But Trump withdrew from that agreement in one of his first acts as president. He has also threatened to scrap the North American Free Trade Agreement.

“Farmers are the president’s people,” Agriculture Secretary Sonny Perdue said in an interview with Morning Edition on Monday. “These are the people that elected the president. The president knows that. These are the people the president cares about. And he wants them to enjoy the American Dream just like all the people in the cities.
