WASHINGTON • As President Donald Trump refuses to allow presumptive President-elect Joe Biden to receive intelligence briefings — even those he was getting during the campaign — an increasing number of Trump’s allies are calling for Biden to have access to the information.

“I just don’t know of any justification for withholding the briefing,” Texas Sen. John Cornyn, a member of the Senate intelligence committee, said Thursday.

“I see no problem with that,” said Iowa Sen. Chuck Grassley, the Republican Party’s longest-serving senator.

“I think so, yes,” said Senate Judiciary Committee Chairman Lindsey Graham, one of Trump’s closest confidants, when asked if Biden should be briefed.

The Senate Republicans advocated for Biden to receive the classified national security information even as they refused to acknowledge that the Democrat has won the presidential election, citing Trump’s baseless claims of fraudulent votes.

“At this point at least, I think he should absolutely be getting intelligence briefings,” Missouri Sen. Josh Hawley said of Biden.

“The briefings he’s been getting as a candidate should continue. I think he should continue to get what he’s been getting and then let’s get on with the resolutions on some of these disputes.”

The GOP pile-on supporting the intelligence briefings amounted to miniscule cracks in support for Trump as he refuses to concede the race, but was also in line with Republicans’ occasional, carefully worded answers about his actions during his presidency. While only a handful of Republicans have called Biden the president-elect, most were comfortable Thursday challenging the Trump administration on withholding intelligence information.

“Both sides need to have access to the information because we don’t know who the president is going to be, so allow that part of this process to still continue just for the sake of national security,” said Sen. James Lankford, echoing Trump’s unsubstantiated claims of voting problems.

Lankford said he would pressure Trump administration bureaucrats to move ahead with the process of transition so Biden could be read in on classified matters. He said Wednesday that he would “get involved” if that didn’t move forward.

For now, the office of National Intelligence Director John Ratcliffe, an ally to Trump, says it can’t begin talking with the Biden’s team until the government starts transition process.
