Tonight on Special Report with Brit Hume:

A homicide bomber dressed as an ultra-Orthodox Jew blows himself up on a bus in downtown Jerusalem, killing 15 people and wounding scores of others. The Hamas (search) militant group claimed responsibility for the attack.

Plus:

Where are the weapons of mass destruction (search)? The Bush administration says they're concealed in Iraq and will be found. But critics claim President Bush hyped intelligence information to gain support for going to war with Iraq. Now, U.S. senators are taking a closer look at the intelligence given to the president.

Retiring chief U.N. weapons inspector Hans Blix (search) lashes out at "bastards" in the Bush administration who he said consistently undermined his efforts to find Iraqi weapons of mass destruction and "leaned on" his staff to tailor their reports.

Despite a sharp reprimand from President Bush, Israeli Prime Minister Ariel Sharon remains unapologetic about the botched assassination attempt on Hamas co-founder Abdel Aziz Rantisi (search).

President Bush is looking to prod lawmakers into quickly giving millions of seniors a prescription drug benefit and choice in health care coverage as Congress fashions far-reaching new Medicare legislation.

House Republican leaders, yielding to pressure from the Senate and White House to expand the child tax credit for low-income families, up the ante with an $82 billion package that also extends the child credits to higher-income couples and includes tax breaks for the armed forces.

Details on those stories and more on Special Report with Brit Hume.
