U.S. lawmakers are continuing to put pressure on the Federal Reserve.

A group of U.S. House members Friday urged the Fed to extend a program to help the troubled commercial real estate market, all while others on Capitol Hill pressed the central bank to disclose the names of Wall Street firms that have received extraordinary aid.

Rep. Paul Kanjorski, a Pennsylvania Democrat who heads a key House Financial Services subcommittee, and dozens of other lawmakers sent a letter to Fed Chairman Ben Bernanke and Treasury Secretary Timothy Geithner, urging them to extend the Term Asset-Backed Securities Loan Facility, or TALF, through 2010. Announcing an extension by mid-August would go a long way to help support the commercial real estate market, they said.

The central bank launched TALF to help jumpstart the market for securities backed by consumer and business loans. In their letter, lawmakers Friday said the program needs to be extended to provide greater support for the "teetering" commercial real estate industry.

"The $6 trillion commercial real estate market has recently experienced a massive credit shortfall, which the TALF program has only just begun to help stabilize," Kanjorski said in a statement Friday. "While I would like to wind down the government's emergency support for the private sector as quickly as possible, we need to provide more time for the TALF program to work in this industry, especially with $1 trillion in commercial real estate debt maturing in the near future."

Such an extension isn't out of the question. Bernanke told lawmakers last week the Fed would be willing to extend the program into next year if the markets still required support.

Meanwhile, congressional calls for the Fed to shed more light on its lending programs have yet to ease up.

A separate group of lawmakers in the Senate on Friday sent a letter to Bernanke, urging him to release a full list of Wall Street firms that have received extraordinary aid.

"It is not justifiable to have the Federal Reserve Board fail to provide this information," said the group, which includes lawmakers such as Sens. Charles Grassley, R-Iowa, Byron Dorgan, D-N.D., and Bernard Sanders, I-Vt.

In the letter, the senators argued that with Goldman Sachs Group Inc. (GS) and other firms reporting large profits, there isn't any reason for the Fed to keep secret the names of financial firms that have received emergency assistance from the central bank.

The senators aren't alone in their concerns about transparency at the Fed. A growing number of lawmakers, frustrated over central-bank rescues of firms such as American International Group Inc. (AIG), have criticized the central bank for being shrouded in secrecy. Earlier this month, a bipartisan group of lawmakers from the House of Representatives wrote a letter to President Barack Obama asking for an investigation of the central bank. They questioned the Fed's role in fostering Bank of America Corp.'s (BAC) acquisition of Merrill Lynch & Co., as well as the Obama administration's plans to grant the central bank new powers to oversee the U.S. financial system.

Senators on Friday said they are specifically concerned about a lack of transparency surrounding the central bank's use of a special emergency authority to lend in "unusual and exigent circumstances" to address problems threatening the financial system. Amid financial panic last year, the Fed invoked the authority in an unprecedented decision to allow investment banks to access direct lending from the central bank.

"In light of recent announcements by Goldman Sachs, J.P. Morgan Chase (JPM), and others that are reporting very large profits after paying back the TARP [Troubled Asset Relief Program] funds to the U.S. government, we don't believe there is now any reason for the Federal Reserve Board to refuse to share information about the companies that were helped by its activities as well as the specific amount of such help for each company," the senators wrote.

They continued in the letter: "We now urge you to release the names of financial institutions that have received the emergency assistance and how much each has received. The American taxpayers' funds have been placed at risk, and we believe the American people deserve a thorough examination of the Federal Reserve Board's Wall Street bailout activities to determine how these funds were used."
