Washington (CNN) President Donald Trump's former attorney Michael Cohen remains on track to testify before Congress in February, but he is concerned for his family, two sources familiar with the matter told CNN.

Cohen agreed to testify before the House Oversight Committee on February 7. One of the sources said Cohen is concerned that a public hearing would make things worse for his family and is concerned about their safety. Trump publicly suggested in a Fox News interview over the weekend, without providing evidence, that he is aware of damaging information about Cohen's family.

The source said Cohen was glad that the chairman of the committee, Rep. Elijah Cummings, D-Maryland, put out a strong statement condemning Trump's remarks to Fox.

"It is unacceptable for anyone -- including the President -- to try to bully or intimidate our witnesses, to try to get them not to testify, to try to scare or threaten their family members, or to try to interfere with Congress' search for the truth," Cummings said earlier this week. "Our Committee has a long and bipartisan history of protecting the ability of witnesses to provide their information to us without even the appearance of intimidation or retaliation."
