So...they WOULDN'T follow him off a cliff?

Trump’s Senate allies on Monday stopped short of echoing Trump’s claim that Obama acted illegally when the Justice Department began probing incoming national security adviser Michael Flynn in late 2016. And they indicated that the Senate would pass on investigating the former president as they conduct their own investigations that could soon ensnare other senior Obama administration officials.

“I’m not anticipating calling President Obama,” said Senate Judiciary Chairman Lindsey Graham (R-S.C.), whose panel is investigating the origins of the 2016 Russia investigation, even as he vowed to bring in former senior Obama administration officials as witnesses.

Senate Republicans [...] sidestepped questions of whether the Justice Department should pursue criminal investigations against the former Obama officials, instead deferring to the ongoing investigation of U.S. Attorney John Durham, who was tapped by Attorney General Williams Barr to probe the origins of the FBI’s investigation of the Trump campaign’s contacts with Russia.

Trump allies have honed in, in particular, on a Jan. 5, 2017 meeting of the outgoing Obama national security team during which the Russia investigation was a topic. Obama attended the meeting, along with then-Vice President Joe Biden and other senior intelligence and Justice Department officials. Flynn’s calls with Russia’s former ambassador to the U.S. Sergey Kislyak were a subject of the meeting, according to multiple accounts by participants shared with investigators.

Chuck Grassley (R-Iowa), said new questions raised about the prosecution of Flynn should be put directly to Obama and Biden.

“Given all we know now about the fake foundation of the inquiry, it's time we ask: What did Obama and Biden know and when did they know it?” Grassley said Monday on the Senate floor.

But Grassley, too, stopped short of saying the Senate should use its powerful committees to investigate the former president, or that the Justice Department should go after Obama. Rather, he and other Senate Republicans simply agreed that Trump’s fury was justified.

Though many of them supported special counsel Robert Mueller’s investigation into Russian election interference while it was active, those same GOP senators have soured on the probe, citing recently released FBI documents that the president’s allies have said is evidence that holdover officials from the Obama administration sought to unfairly target high-level Trump associates like Flynn.

They soured on it long before now. They soured on it when it laid out all of the Trump cabal's crimes, which is why Barr came out with a misleading statement about the Mueller report.

Those lawmakers have in particular directed their ire at FBI Director Christopher Wray, accusing him of not doing enough to “clean up” the agency after Comey and former FBI Deputy Director Andrew McCabe were removed from their posts.

Trumpland is never at a loss for scapegoats.

Senate Republicans have also largely avoided the posture adopted by Trump’s closest House allies, who have echoed his demands that Obama himself, or his top aides, be targeted by investigators.

“Nobody more than me wants to see these people prosecuted,” Rep. Devin Nunes of California, top Republican on the House Intelligence Committee, said in a radio appearance on KMJ when asked about senior Obama administration officials being held legally accountable for their role in the Flynn saga.

Is there anybody Nunes doesn't want to see prosecuted?

...but hey, do what you want...you will anyway.
