House Speaker Paul Ryan announced Wednesday that he will not seek re-election and will retire in January.

"You all know I did not seek this job," Ryan said, addressing reporters. "I took it reluctantly. ... I have no regrets."

Ryan, 48, cited wanting to be around his adolescent children more often.

The latest flash point in the nation's gun debate sent millions of Americans marching into the streets over the weekend in cities like Denver to call for stricter gun laws.

"I've never, until this year I haven't contributed a dime in my entire life to anybody's campaign. This year? I've given more money than I ever thought I would do," said David Frieder, a retiree who attended Saturday's gun march in downtown Denver.

Top Republican lawmakers do not support legislation aimed at protecting Department of Justice special counsel Robert Mueller and his Russia investigation from White House interference, insisting that it is unnecessary.

"The special counsel should be free to follow through his investigation to its completion without interference, absolutely," House Speaker Paul Ryan, R-Wis., told reporters Tuesday. "I am confident that he'll be able to do that. I have received assurances that his firing is not even under consideration."

Marcy Kaptur didn't plan for this.

First elected in 1982, the Ohio Democrat didn't set out to become the longest-serving woman in House history.

"The reasons that I ran, to change certain practices and policies, [I thought] could be done much more quickly," she said in an interview with NPR. On Sunday, Kaptur becomes the longest-serving woman ever to serve in the chamber with a tenure that spans 35 years, two months and 15 days.

Congress has the power to challenge President Trump on new tariffs, but it's unlikely lawmakers will act, even though nearly all congressional Republicans oppose the president's trade policy because they believe it will harm the U.S. economy.

"It's a conundrum, really, because you do not want 100 senators and our counterparts in the House doing basically any trade initiative. That's why we give that (power) to the executive," said Senate Agriculture Committee Chairman Pat Roberts, R-Kan.

Fears of economic and political backlash are motivating senior congressional Republicans to move forward this week with public and private lobbying efforts aimed at getting President Trump to change his mind about tariffs he intends to levy on steel and aluminium imports.
