McAllen, Texas (CNN) A group of more than a dozen House Democrats toured border detention facilities in McAllen, Texas, on Saturday, recounting "inhumane" conditions including overcrowded cells, rampant disease, and asylum seekers who had not washed or brushed their teeth for weeks.

California Rep. Jackie Speier, who led the delegation, called it a "profound experience" to be there and tour the facilities. She praised the Border officers for "doing the best they can with what they have," but, like Pence, called for congressional action.

"We intend to go home back to Washington, DC, and we're going to develop a legislative package" as the first step "to address this humanitarian crisis," she said, noting that members of Congress also need to travel to Northern Triangle countries and assess the resources available there.

Speier and Rep. Annie Kuster of New Hampshire, who was also on the trip, both described seeing about 40 men in cells meant to accommodate less than a dozen occupants at the first facility.
