About 70 volunteers from Planned Parenthood were greeted by the locked congressional office of House Speaker Paul Ryan on Friday when they went to deliver petitions bearing 90,000 signatures from people who say they do not want the organization defunded.

It's unclear why the Wisconsin Republican's congressional office was closed, but the House was in recess from about noon to 1 p.m., the period during which volunteers arrived. After that recess, lawmakers met to certify the Electoral College ballot count granting Donald Trump victory in the November presidential election.

An email to a Ryan staffer was not immediately returned, and according to a Planned Parenthood spokesman, police said the office was not open and only took appointments. A photo posted by Planned Parenthood Action Fund on social media also showed a sign on Ryan's office door saying "only scheduled appointments will be admitted."

Ryan on Thursday confirmed that a budget-process bill set to repeal portions of President Barack Obama's health care law, the Affordable Care Act, will carry language aimed at stripping Planned Parenthood of federal funding.

"Paul Ryan may have locked his doors, but he can't drown out our voices," Erin Carhart, manager of youth organizing for Planned Parenthood Action Fund, says in an email. "People are already worried they'll lose their health care, that they'll lose their birth control, and now Paul Ryan is trying to take away Planned Parenthood."

Planned Parenthood is continuing to collect petition signatures and also has made 15,000 calls to Ryan's office. The petitions on Friday filled five boxes.

"This politically motivated move by Speaker Ryan will only serve to prevent patients covered by Medicaid from choosing the best reproductive health care available to them," Rahula Strohl, a volunteer for Planned Parenthood Action Fund, also says in an email.

Under the Hyde Amendment, federal funds are barred from going toward most abortions, with exemptions for rape, incest or a woman's health. Organizations like Planned Parenthood still can use federal funding to provide birth control, cancer screenings and other services related to reproductive health.

The Congressional Budget Office has previously estimated that Planned Parenthood receives about $450 million annually in federal funding, the bulk of it from Medicaid reimbursements.

Members of Congress who are opposed to abortion have been in favor of defunding Planned Parenthood for years, but the effort received renewed interest following the 2015 release of videos that were heavily edited and appeared to show that the organization worked to illegally profit from the sale of fetal tissue. Investigations have not found Planned Parenthood guilty of illegal activity, and the group has denied any wrongdoing.

Republicans have argued that funding routed to Planned Parenthood should be diverted to health care providers that offer similar services but do not provide abortions.

Upon discovering they couldn't enter the office, the volunteers on Friday instead went to the office of Ryan's fellow Wisconsin lawmaker, Democratic Rep. Gwen Moore. The congresswoman, who supports the organization, took pictures with volunteers and spoke with them.

Moore spokesman Eric Harris says the congresswoman's team had been in the middle of editing a video about the threats posed to Planned Parenthood when volunteers arrived.

"We are trying to show this organization is vital to our constituents," he says. "We have communities of color that depend on organizations like Planned Parenthood for their reproductive services, and to shutter that organization would have a drastic impact on the health of our constituents – both men and women."

Comments from President-elect Donald Trump on Planned Parenthood have been mixed. He said during the primary that the organization did "wonderful things" for women's health but that he was not in favor of abortion and said the organization should be defunded "while they do abortions."
