House Speaker Nancy Pelosi, D-Calif., had planned to move quickly Thursday to hold a vote on a package of measures to address the coronavirus. But a push for changes from the administration and resistance from congressional Republicans put that plan on hold.

The panel that sets rules for floor debate paused its meeting Thursday morning as Chairman Jim McGovern, D-Mass., announced Pelosi was discussing provisions with Treasury Secretary Steven Mnuchin.

"He has some suggestions that we are going to evaluate to see whether these are things that we are going to agree on," McGovern said.

Pelosi's spokesmantweetedthat the speaker and Treasury secretary talked twice about language for the bill.

House Minority Leader Kevin McCarthy of California told reporters the measure "comes up short." He said proposals in the Democratic measure such as sick leave would take six months to implement.

He said the White House, Republicans and the speaker's office were working together, and that lawmakers should postpone their recess by 24 to 48 hours in order to reach a deal.

"Let's do what we can do together right now," he said.

Oklahoma GOP Rep. Tom Cole complained that the bill wasn't released until late Wednesday night and has had "zero Republican input."

"Nobody's prepared to be rolled," Cole said, adding, House Republicans weren't prepared to back the bill and indicated it would have trouble getting the support of GOP senators.

The measure, which was released late Wednesday, includes paid sick leave, unemployment assistance, nutrition aid and help with states.

The virus affected Capitol Hill directly as a staffer to Washington Sen. Maria Cantwell became the first known confirmed case of coronavirus on the campus. The aide has been in isolation since developing symptoms, and the senator has closed her office for cleaning, according to a statement. The aide had "no known contact with the senator or other members of Congress," the statement released Wednesday evening said.

The top House and Senate law enforcement officials announced Thursday that there would be a temporary closures of all tours of the Capitol. They also said the Capitol building and House and Senate office buildings would be limited to members, staff, press and official visitors starting at 5 p.m. on Thursday. The measures are in effect until April 1.

Arkansas Republican Sen. Tom Cotton announced his Washington office would be closed. Sen Ted Cruz, R-Texas, who self-quarantined after he was exposed at a conference to someone who tested positive for the virus also closed his Washington office.
