Things got seriously tense during a House Judiciary Committee hearing Thursday when Rep. Louie Gohmert (R-Texas) and FBI Director Robert Mueller battled over the efficiency of the FBI's investigation into the Boston bombers prior to the April 15 terrorist attack.
Surprisingly, Mueller claimed he wasn't aware that the mosque that the Boston bombing suspects attended, the Islamic Society of Boston, was founded by a convicted supporter of terrorism.
Due to this and other reasons, Gohmert argued not enough was done to prevent the attack as the suspects' radical Islamic ties were overlooked.

"The FBI never canvassed Boston mosques until four days after the April 15 attacks," he said. "If the Russians tell you that someone has been radicalized and you go check and see the mosque that they went to, then you get the articles of incorporation as I have for the group that created the Boston mosque where these Tsarnaevs attended and you find out the name Alamoudi."
Abdurahman Alamoudi, who was convicted and is currently in jail for supporting terrorism, co-founded the mosque that the two Boston bombing suspects attended in Boston, Gohmert lectured.
"And you didn't even bother to go check about the mosque?" he added. "Then when you have the pictures, why did no one go to the mosque and say, 'who are these guys?'"

Mueller then accused Gohmert of not having his facts "together," setting off an explosive exchange.
"Point out specifically," Gohmert began.
"May I finish my--" the FBI boss shot back.
"Sir, if you are going to call me a liar, you need to point out specifically where any facts are wrong," Gohmert said.
Mueller countered by arguing that the FBI was at the Boston mosque months prior to the Boston bombing as a part of its "outreach efforts."
“Were you aware that those mosques were started by Alamoudi?” Gohmert pressed.
"I've answered the question," Mueller said.
"You didn't answer the question, were you aware they were started by Alamoudi?"
"No," the FBI director finally muttered.
"You were not, thank you," Gohmert concluded.

Fox News has more details on the radical Boston mosque:
The mosque where at least one of the two suspected Boston Marathon bombers prayed has a controversial history, with ties to the Muslim Brotherhood, terror funding and frequent fiery sermons, according to a group that has long monitored the house of worship.
The mosque’s founders were in the Muslim Brotherhood and one, Abdurahman Alamoudi, pled guilty in 2004 for conducting illegal transactions with the Libyan government and his partial role in a conspiracy to assassinate Saudi Crown Prince Abdullah, Hale said. Alamoudi, who served as an Islamic adviser to President Clinton, was accused by critics of espousing pro-American language while lobbying in Washington, while expressing his support of terror groups Hamas and Hezbollah when addressing Islamist rallies.
Sheikh Ahmed Mansour, who has served on the APT board with Hale and founded the Quranists sect of Islam, leading to his eventual exile from his native Egypt, told FoxNews.com that the rhetoric at the Cambridge mosque gave him a bad feeling.
