Sen. John Cornyn (R-Tex.), Sen.      Lindsey Graham (R-S.C.) and others are standing up for      Attorney General Jeff Sessions after President Trump      suggested he wants Sessions to resign. (The Washington      Post)    
    For arguably the first time, Republicans are starting to draw    red lines in an effort tosavePresident Trump from    himself.  
    As Trump weighs firing one or both of Attorney General Jeff    Sessions and special counsel Robert Mueller, a pair of GOP    senators is promising measures to thwart or dissuade    him.Senate Judiciary Committee Chairman Charles E.    Grassley (R-Iowa) said Wednesday that his panel would not    confirm a new attorney general to replace Sessions this year.    Then Thursday morning, Sen. Lindsey O. Graham (R-S.C.) said he    would introduce legislation to protect Muellerand warned    it could    be the beginning of the end of Trump's presidency if he    tried to fire the special counsel.  
    Both moves are unprecedented.For perhaps the first time,    Senate Republicans with real sway are talking about concrete    steps tocounteract Trump's impulses and prevent    constitutional crises.  
    Republicans have spent plenty of time talking tough    about Trump, mind you. Plenty of them said Trump's comments    about women on that Access Hollywood tape were beyond the    pale, and some even urged him to drop out of the presidential    race. Many of these same members, such as Rep.Jason    Chaffetz (R-Utah), would later embrace Trump. (Chaffetz has    since retired from Congress.)  
    Like Graham, Sen. John McCain (R-Ariz.) has been among the most    vocal Trump critics in the GOP, including givingabrutal    speech denouncing Trump's worldviewin February in    Munich. But even that speech didn't call out Trump by name,    andMcCain has frustrated Trump's opponents by not backing    up his words with actions, such as voting against Trump's    agenda.  
    House Speaker Paul D. Ryan (R-Wis.), too, has been called upon    to occasionally denounce Trump. And sometimes he has obliged.    But he has also assumed a nonconfrontational approach to    dealing with the president, repeatedly brushing off his tweets     including as recently as Thursday morning  in favor of    trying to work with Trump to get things done.  
    There have been some threats of legislation or actions by    Republicans to stop Trump. In January, for instance, GOP    senators led by McCain threatened     a bill to prevent Trump from lifting sanctions against    Russia. Similarly, Graham in March suggested he might call    for     a special committee to look into Trump's baseless allegation    that President Barack Obama wiretapped him.  
    But this is the first time the stakes have been this high. And    Grassley and Graham are going on-record withspecific    actions and threats.  
    Look, politics is an inherently disingenuous business.    Sometimes you say something with a little extra conviction to    send a message, or you make threats that you're not 100 percent    committed to backing up. Politicians also have to deal with the    realities of alienating a president who has significant sway    over whether they can pass their agenda. There is no doubt    Republicans, after denouncing Trump repeatedly on the campaign    trail and seeing him win anyway, have grown gun-shy. This    is the moment he's gone too far and I can cut him off,    they've thought so many times, only to be proven wrong in short    order.  
    I'm not one of those people who thinks McCain can't denounce    Trump one day and vote for his agenda the next. McCain is a    conservative Republican, so he tends to support Republican    legislation. He wants to replace Obamacare, so he voted to move    forward with a debate on doing just that this week, despite his    reservations about the process.  
    But at some point, Republicans who think Trump is truly    flirting with a constitutional crisis will need to back up    their tough rhetoric with actions. Grassley and Graham seem to    be at least edging toward doing that  perhaps recognizing the    uniquely fraught options Trump is apparently considering.  
    We'll see how much follow-through there is. But at some point,    the rubber must meet the road, or it just amounts to a bunch of    talk.  
    Update: Sen. Ben Sasse (R-Neb.) is also speaking out now,    telling Trump not to plan on a possible recess appointment to    replace Sessions. "Forget about it," Sasse said. Sasse didn't    appear to threaten specific action, though     Republicans as a whole could thwart a recess    appointment.
