Washington (CNN) Republican lawmakers are bracing for the White House to unveil the President Donald Trump's position on guns, divided over what steps they hope the President will take and clinging to any word from administration officials on where he might be leaning.

Attorney General William Barr was on the Hill Tuesday afternoon to talk with members about guns, and he has been in contact with lawmakers directly, but Senate Judiciary Chairman Lindsey Graham said Barr still wasn't clear where Trump stood on background checks.

"They're still talking," Graham said after having talked to the attorney general on Monday. "We're trying out some new ideas on expanded background checks."

Barr has suggested to the President personally that he consider expanded background checks, noting law enforcement support for universal checks, according to a US official briefed on the matter. But some of the President's domestic policy aides, who have the upper hand on the issue, have fought against any such move.

Barr is expected to return Wednesday for more discussions, according to a US official briefed on the matter.
