WASHINGTON (AP) — The Latest on President Donald Trump and immigration (all times local):

12 p.m.

President Donald Trump says he'll be signing something "in a little while" to address the spike in the number of migrant children being separated from their families at the border.

Trump said during a White House meeting with members of Congress that, "We want to keep families together."

The comments come amid news that Homeland Security Secretary Kirstjen Nielsen has been working on executive action that would end the separation process.

Trump also told reporters that he plans to cancel the annual congressional picnic, saying: "It doesn't feel right to have a picnic for Congress."

He added that: "We want to solve this immigration problem."

British Prime Minister Theresa May says the United States is wrong to separate migrant children from their parents, but has rejected calls to cancel President Donald Trump's visit to Britain next month.

May said Wednesday that images of children in cages were "deeply disturbing. This is wrong. This is not something that we agree with."

Opposition lawmakers rebuked May for not criticizing the Trump administration in stronger terms.

Trump is due to meet May and Queen Elizabeth II during a visit to Britain on July 13.

May said Britain and the United States had a "special, long and enduring relationship," and she had "a range of issues" to discuss with Trump.

She said the close U.K.-U.S. bond meant "when we disagree with what they are doing, we say so."

Homeland Security Secretary Kirstjen Nielsen is drafting an executive action for President Donald Trump that would direct DHS to keep families apprehended at the border together during detention.

That's according to two people familiar with her thinking who spoke on condition of anonymity to discuss the effort before its official announcement.

It's unclear whether the president is supportive of the measure.

But Nielsen is on her way to the White House to discuss the issue with the president's team, according to one of the people.

The person says the secretary believes there is little certainty that Congress will act to fix the separation issue and is trying to find a solution. The order would ask the Department of Defense to help house the detained families.
