Special counsel Robert Mueller likely will testify later this month before the House Judiciary Committee, a contrary tweet sent Sunday by Donald Trump notwithstanding.

That’s according to CNN White House reporter Jim Acosta.

Although the details hadn’t been nailed down, arrangements were being made for Mueller to testify May 15 before the House Judiciary Committee, when over the weekend, Trump appeared to put the breaks on that. He sent an angry tweet saying that Mueller should not testify.

Lawmakers, particularly House Democrats, have been looking forward to Mueller’s testimony in order to answer questions left unanswered from his two-year investigation into Trump, his 2016 campaign, and any subsequent obstruction of justice.

“According to the source familiar with all this who I spoke with a short while ago, the view inside the White House is that the president was just expressing his opinion when he made that statement and that tweet over the weekend that he’s not necessarily issuing a directive or order to his administration to block Robert Mueller from testifying,” Acosta said. “Essentially with the president saying he views this investigation is over and that it’s time to move on but, interesting there are sources inside administration familiar with this matter essentially saying the president was letting off steam there, not necessarily signaling at this point that he’s going to block the special counsel from testifying.”
