Senator Bob Corker of Tennessee, the chairman of the Foreign Relations Committee and one of Mr. Trump’s most unapologetic backers on Capitol Hill, suggested this week that Mr. Trump had “a crucial two- or three-week period” to smooth out his rougher edges or put his nomination in jeopardy.

.. The most prominent voice to call for Mr. Trump’s ouster since his attack on Judge Curiel has been that of Hugh Hewitt, a talk-radio host who is respected in conservative circles but has no role in the nomination process.
