Washington - The chairman of the House intelligence committee says that President Donald Trump’s decision to reveal House Speaker Nancy Pelosi’s trip to Brussels and Afghanistan is “completely and utterly irresponsible in every way.”

House Intelligence Committee Chairman Adam Schiff says he won’t comment on whether the trip is still on. Trump announced Thursday afternoon that he was denying Pelosi an aircraft to visit troops abroad and reassure NATO allies. That move came after Pelosi suggested delaying his State of the Union address.

Schiff says Trump is acting “like he’s in the fifth grade.” The California Democrat said that “we’re determined our oversight will continue no matter what the president’s action are.”

Schiff said the congressional delegations had anticipated defense and intelligence briefings in Afghanistan.

A spokesman for Pelosi says the trip was intended to express appreciation to U.S. troops and reaffirm the United States “ironclad commitment” to the NATO alliance.

Trump wrote Pelosi on Thursday and said he was denying military aircraft for a trip to Egypt, Brussels and Afghanistan amid the government shutdown. The notice came after Pelosi attempted on Wednesday to delay Trump’s State of Union address.

Pelosi spokesman Drew Hammill tweeted that the previously unannounced trip was to Afghanistan, including a stop in Brussels. He said it did not include a stop in Egypt.

Hammill said Pelosi was to meet with top NATO commanders and troops and “obtain critical national security & intelligence briefings from those on the front lines.”

Senate Judiciary Chairman Lindsey Graham says Trump’s decision to deny Pelosi aircraft is “inappropriate.”

The Republican and frequent Trump ally also criticized Pelosi for her attempt to delay Trump’s State of Union address amid their government shutdown clash. He called that “blatantly political.”

Graham said “one sophomoric response does not deserve another.”

House Majority Leader Steny Hoyer criticized Trump’s decision, calling it “petty,” ‘‘small” and “vindictive.” The Maryland Democrat said it was “unbecoming of the president of the United States.”

In turn, House Republican Leader Kevin McCarthy blasted Pelosi, asking why she would leave the country when the government is shut down.

McCarthy said to Pelosi: “You’re speaker of the house.”
