(CNN) Vice President Mike Pence is keeping quiet during yet another raucous news week for the Trump administration.

During a brief media availability on Wednesday in Rockport, Texas, Pence shook his head with a nonverbal nonresponse to a question about Paul Manafort's conviction and Michael Cohen's plea deal.

Pence, who was on a two-day trip Wednesday and Thursday to Texas and Louisiana, was asked several more times -- over the roar of Air Force Two's engines -- if he had any reaction to or concern over the news about President Donald Trump's former campaign chairman and his former longtime attorney. Pence did not engage.

It is a familiar posture for Pence, who steers clear of palace intrigue and drama in the White House. When Rob Porter, a former White House staff secretary, was accused of assaulting his ex-wives in February, Pence told reporters he did not know about the allegations and firing of Porter until after it had happened. He did not offer an answer at the time when asked why he seemed out of the loop on the matter, responding that he was honored to serve the President.

He and aides have also maintained for months that he had no knowledge of former White House national security adviser Michael Flynn's communications about Russian sanctions with the Russian ambassador during the Trump transition. Flynn was dismissed weeks after Trump took office for misleading Pence and others about that contact.
